Release 0.9
Last revised July 29, 2009
This software is OSI Certified Open Source Software.
OSI Certified is a certification mark of the Open Source Initiative.
Preamble
1. Target Operating Environments
2. Compatibility with Previous Releases
3. Known Issues
4. Running Eclipse
Preamble
The e4 0.9 release is a technology preview from the Eclipse Project's e4 incubator. The projectis making a release available at this early stage to solicit feedback and wider participationin the project. This release is quite unlike the stable, mature releases people have cometo expect from the Eclipse project. The software has bugs, and has not been heavily testedfor quality, internationalization, usability, performance, or accessibility. Having said that, this release is a preview of some exciting new technology that will make Eclipse-based applicationsmore flexible, easier to program, and interoperable with a wider range of programminglanguages and runtime environments. We encourage developers to look past the roughedges of this early release to the explore the new underlying technology, try the e4 demos, provide feedback, and participate in its further development.
1. Target Operating Environments
In order to remain current, each e4 Project release targets reasonably current operating environments.
Most of the e4 Project is 'pure' Java code and has no direct dependence on the underlying operating system. The chief dependence is therefore on the Java Platform itself. Portions are targeted to specific classes of operating environments, requiring their source code to only reference facilities available in particular class libraries (e.g. J2ME Foundation 1.0, J2SE 1.3 and 1.4, etc.). In general, the 0.9 release of the Eclipse Project is developed on Java SE 5.
e4 has dependencies on components from other Eclipse projects, notably the Platformproject, and the EMF project. While specific version dependencies may specifya wider range, e4 is generally built and tested against the versions contained in the Galileo release train.
There are many different implementations of the Java Platform running atop a variety of operating systems. We focus our testing on a handful of popular combinations of operating system and Java Platform; these are our reference platforms. Eclipse undoubtedly runs fine in many operating environments beyond the reference platforms we test. However, since we do not systematically test them we cannot vouch for them. Problems encountered when running Eclipse on a non-reference platform that cannot be recreated on any reference platform will be given lower priority than problems with running Eclipse on a reference platform.
Forever And Always 0.9 Demo Mac Os Downloads
e4 also has dependencies on browser technologies such as JavaScript and Flash. Thereference platforms listed below show the versions of these technologies that weare developing and testing against.
e4 0.9 is tested and validated on the following reference platforms:
| Reference Platforms |
Microsoft Windows Vista, x86-32, Win32 running (any of):
|
Microsoft Windows XP, x86-32, Win32 running (any of):
|
Red Hat Enterprise Linux 5.0, x86-32, GTK running (any of):
|
Apple Mac OS X 10.5, Universal, Cocoa running:
|
As stated above, we expect that e4 works fine on other current Java VM and OS versions but we cannot flag these as reference platforms without significant community support for testing them.
2. Compatibility with Previous Releases
Compatibility of e4 0.9 with previous Eclipse project releases
Portions of e4 will be compatible with Eclipse 3.5 (and all earlier 3.x versions).However, compatibility is not a primary focus for this initial release of e4, and thereis no firm promise of compatibility between e4 and earlier Eclipse releases of any kind.Compatibility with Eclipse 3.x is anticipated to be a major focus of the subsequent e4 release.
Workspace Compatibility: e4 0.9 will be upwards workspace-compatible with earlier 3.x versions of the Eclipse SDK unless noted. This means that workspaces and projects created with Eclipse SDK 3.5 .. 3.0 can be successfully opened by e4 0.9 and upgraded to an e4 workspace. This includes both hidden metadata, which is localized to a particular workspace, as well as metadata files found within a workspace project (e.g., the .project file), which may propagate between workspaces via file copying or team repositories. Individual plug-ins developed for e4 0.9 should provide similar upwards compatibility for their hidden and visible workspace metadata created by earlier versions; 0.9 plug-in developers are responsible for ensuring that their plug-ins recognize metadata from earlier versions and process it appropriately. User interface session state may be discarded when a workspace is upgraded. Downward workspace compatibility is not supported. A workspace created (or opened) by a product based on e4 0.9 will be unusable with a product based an earlier version of Eclipse. Visible metadata files created (or overwritten) by e4 0.9 will generally be unusable with earlier versions of Eclipse.
Non-compliant usage of API's: All non-API methods and classes, and certainly everything in a package with 'internal' in its name, are considered implementation details which may vary between operating environment and are subject to change without notice. Client plug-ins that directly depend on anything other than what is specified in the Eclipse SDK API are inherently unsupportable and receive no guarantees about compatibility within a single release much less with earlier releases. Refer to How to Use the Eclipse API for information about how to write compliant plug-ins.

3.1 General problems
3.1.1 General - Startup
Installation/Configuration issues that can cause Eclipse to fail start
Here are some common problems that can cause Eclipse not to start:
- As shown above, Eclipse e4 0.9 requires at least a Java SE 5 VM. Perhaps an older version of the VM is being found in your path. To explicitly specify which VM to run with, use the Eclipse -vm command-line argument. (See also the Running Eclipse section below.)
- Running Eclipse on Gentoo Linux may result in the following error message: * run-java-tool is not available for sun-jdk-1.6 on i686If this occurs, start Eclipse by specifying a -vm argument, eitherspecify the path to a java vm or use: eclipse -vm `java-config--java` (bug 176021)
* IMPORTANT: some Java tools are not available on some VMs on some architectures - Eclipse must be installed to a clean directory and not installed over top ofa previous installation. If you have done this then please re-install to a newdirectory. If your workspace is in a child directory of your old installationdirectory, then see the instructions below on 'Upgrading Workspace from aPrevious Release'.
- Java sometimes has difficulty detecting whether a file system is writable. Inparticular, the method java.io.File.canWrite() appears to return true inunexpected cases (e.g., using Windows drive sharing where the share is aread-only Samba drive). The Eclipse runtime generally needs a writableconfiguration area and as a result of this problem, may erroneously detect thecurrent configuration location as writable. The net result is that Eclipse willfail to start and depending on the circumstances, may fail to write a log filewith any details. To work around this, we suggest users experiencing thisproblem set their configuration area explicitly using the -configuration commandline argument. (bug 67719)
Invalid characters in install directory prevents Eclipse from starting
Eclipse will fail to launch if installed in a directory whose pathcontains certain invalid characters, including :%#<>'!. Theworkaround is to install Eclipse in a directory whose path does not containinvalid characters. (bugs 3109and 17281)
Hanging during class loading when out of permanent generation memory
The Sun VM may hang indefinitely during class loading if it runs out of permanentgeneration memory. This will cause CPU usage to stay at 100% until the processis ended. See the section Running Eclipse for detailson addressing this VM problem.
3.1.2 General - GCJ
GCJ is an effort by the GCC team to provide an open source Java compiler andruntime environment to interpret Java bytecode. Unfortunately, the GCJ runtimeenvironment is not an environment that is often tested on by Eclipse developers.
The most common problems surrounding GCJ are:
- Eclipse does not start at all
- Eclipse throws a 'java.lang.ClassNotFoundException: org.eclipse.core.runtime.Plugin' that can be found in the logs (located inworkspace/.metadata/.log)
The workspace's log file is a good place to check to identify whether GCJ isbeing used or not. Every Eclipse log session is prepended withinformation about the runtime environment that was used to run Eclipse. The logmay include something like the following:
java.fullversion=GNU libgcj 4.2.1 (Debian 4.2.1-5)If Eclipse does start, one can check which runtime environment is being used torun Eclipse by going to Help > About Eclipse SDK > Installation Details > Configuration. TheAbout dialog itself can also provide other information, the build identifiercan be of particular interest as it is tagged by some distributions. This allows theuser to identify whether Eclipse was downloaded through the distribution'spackage management system or directly from the eclipse.org website.
Eg:Build id: M20070212-1330 (Ubuntu version: 3.2.2-0ubuntu3)The two most common workarounds are:
- download the Eclipse binary from eclipse.org directly
- run Eclipse using an alternate Java runtime environment
To download e4, visit the e4 download page:
It is imperative that 64-bit builds are downloaded and used if a 64-bit Javaruntime environment has been installed. Below are two sample tarball names ofversion 3.5.0 of the Eclipse SDK packaged for 32-bit and 64-bit processors.To run Eclipse with an alternate Java runtime environment, the path to the Javavirtual machine's binary must be identified. With an Eclipse installation fromthe distribution, altering the $PATH variable to include the path to thealternate Java runtime environment is often not enough as the Eclipse thatLinux distributions package often performs a scan internally to pick up GCJ byitself whilst ignoring what's on the $PATH. An example of the terminal's outputis shown below:
searching for compatible vm...
testing /usr/lib/jvm/java-7-icedtea...not found
testing /usr/lib/jvm/java-gcj...foundOnce the path to the virtual machine's binary has been identified, try runningEclipse with the following command:
./eclipse -vm /path/to/jre/bin/javaFor an actual example, it might look something like the following:
./eclipse -vm /usr/lib/jvm/sun-java-6/bin/java
./eclipse -vm /opt/sun-jdk-1.6.0.02/bin/javaIf this seems to solve the problem, it is likely that the problem really wasrelated to the use of GCJ as the Java runtime for running Eclipse. Theeclipse.ini file located within Eclipse's folder can be altered toautomatically pass this argument to Eclipse at startup. An example of itscontent is presented below:
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
/opt/sun-jdk-1.6.0.02/bin/java
-vmargs
-Xms40m
-Xmx512mNote that every argument must be on its own line. More information about theeclipse.ini file can be found at http://wiki.eclipse.org/Eclipse.ini.
If problems persists after downloading an installation of Eclipse fromeclipse.org and using a supported Java runtime environment (a list of which may be found above), you can seek further assistance through the newsgroups, the IRC channel, and/or bugzilla.
3.1.3 General - 64-bit Java HotSpot(TM) VM
There is a known issue with the Java HotSpot(TM) 1.6.0 VM compiler which causes eclipse to crash (see Sun bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6614100,and Eclipse bug 214092).The crash usually occurs within a VM CompilerThread when attempting to compile the method org.eclipse.core.internal.dtree.DataTreeNode.forwardDeltaWith.
This problem has been addressed in Sun Java 6 update 11, so the simplest resolution isto obtain the latest JRE release for your platform.To work around the issue you can exclude the method org.eclipse.core.internal.dtree.DataTreeNode.forwardDeltaWith from being compiled with the followingVM argument:
-XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/DataTreeNode,forwardDeltaWithThis VM argument can be placed in the eclipse.ini file after the -vmargs line like the following:
-startup
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090306-1900
--launcher.library
plugins/org.eclipse.equinox.launcher_1.0.200.v20090429-1630.jar
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/DataTreeNode,forwardDeltaWith
-Xms40m
-Xmx256m
There have been reports of other classes that cause the compiler to crash. If all else fails you can disable the compiler with the VM arg '-Xint'.
3.2 e4 Compatibility Platform
Workbench layout is not restored
When you shutdown and restart the workbench, any changes you made to the workbenchlayout are not persisted. The e4 compatibility platform always opens in the defaultperspective with the default layout.(bug 284473). As a side effect, youwill sometimes see errors when closing the workbench, but they won't cause problems.
Web UI does not work on Mac OS X
On Mac OS X, the embedded web UI does not currently work due to a Jetty configuration problem. As a workaround, add '-Dorg.eclipse.equinox.http.jetty.http.port=8080' to the end of the eclipse.ini file. (bug 284433).
Debugging with multiple copies of a source editor open
When hitting a debug breakpoint, if the source editor has already been open ina non-debug perspective, the duplicate source editor might not appear in thedebug perspective or might not get scrolled to the breakpoint location.
This problem should be eliminated once the support for shared model parts isimplemented. For details please see bug 284610.
Views have missing toolbar buttons
The Outline view is missing its toolbar buttons, and the Synchronize view only opens withtwo buttons. Closing and then re-opening the Synchronize view after a sync operation willrestore its buttons. (bug 284387).
No main toolbar
The main menu is available, but support for the main toolbar is not currently hooked up. (bug 269269).
Cannot open second Console or Properties views
Multi-instance views such as the Console or Properties view cannot be openedor the second view functions incorrectly. Please see bug 279807 for details.
Cannot close the last perspective
When there is only one perspective open, it cannot be closed. The workaround is toopen another perspective before closing the one you no longer want to use (bug 285081).
Cannot open a file in the internal web browser editor
You can open the Interal Web Browser view, but if you double-click on a filein the Package Explorer or use Open the file will be opened in anexternal web browser.(bug 284050).
Cannot type in a editor sometimes after clicking on a tab
Sometimes if you switch editors by clicking on the tab, focus goes to the taband you can't type in the editor. The workaround is to <TAB> (which will movefocus into the editor) or simply click in the editor.(bug 285001).
Changing theme in the Appearance Preferences prevents workspace startup
3.x themes will not work with the CSS support enabled. They should not be used.Once in this state, the only option is to open in another workspace.(bug 285166).
3.3 e4 Components
3.3.1 XWT
XWT Editor does not support Cocoa
On Mac OS X, the XWT editor does not currently support Cocoa. The XWT editor canonly be used when running on Carbon (bug 282358).
3.3.2 SWT
SWT/BE only available on Flex
Although there has been some work on porting SWT/BE to both JavaScript/Dojo andSilverlight, the 0.9 release only includes support for the ActionScript/Flex port. Otherports may become available in the future depending on level of interest.
3.3.3 Declarative Styling
ETabFolder body / tab keylines don't line up
Although the top and bottom border colors of the ETabFolder can be setdifferently, e.g.
ETabFolder {
border-top-color: rgb(246, 246, 251);
border-bottom-color: rgb(201, 200, 204);
}
The lines don't match up quite right. Thus in practice, you should just useborder-color:. However, if you wish to experiment with this, there is a patchin bug 283882 to fix this.
3.4 e4 Demos
Photo demo thumbnails view doesn't update when photos are added
The e4 photo demo doesn't show photo thumbnails immediately after adding addingphotos to an album. Selecting another album in the Albums view and thenswitching back will cause the Thumbnails view to update. For details seebug 285014.

4.1 Running the e4 SDK
After installing the e4 SDK in a directory, you can start the Workbenchby running the Eclipse executable included with the release (you also need a Java SE 5JRE, not included with the Eclipse SDK). On Windows, the executable file is called eclipse.exe,and is located in the eclipse sub-directory of the install. Ifinstalled at c:e4-0.9-win32, the executable is c:e4-0.9-win32eclipseeclipse.exe.Note: Set-up on most other operating environments is analogous. Specialinstructions for Mac OS X are listed below.
Allocating enough memory and solving OutOfMemoryErrors
By default, Eclipse will allocate up to 256 megabytes of Java heap memory. This shouldbe ample for all typical development tasks. However, depending on the JREthat you are running, the number of additional plug-ins you are using, andthe number of files you will be working with, you could conceivably have to increase this amount. Eclipse allows you to pass arguments directly to the Java VM using the-vmargs command line argument, which must follow all other Eclipse specific arguments.Thus, to increase the available heap memory, you would typically use:
eclipse -vmargs -Xmx<memory size>
with the <memory size> value set to greater than'256M' (256 megabytes -- the default).
When using a Sun VM, you may also need to increase the size of the permanentgeneration memory. The default maximum is 64 megabytes, but more maybe needed depending on your plug-in configuration and use. When the VM runsout of permanent generation memory, it may crash or hang during class loading.This failure is less common when using Sun JRE version 1.5.0_07 or greater.The maximum permanent generation size is increased using the -XX:MaxPermSize=<memory size> argument:
eclipse -vmargs -XX:MaxPermSize=<memory size>
This argument may not be available for all VM versions and platforms; consult your VM documentationfor more details.
Note that setting memory sizes to be larger than the amount of available physicalmemory on your machine will cause Java to 'thrash' as it copies objectsback and forth to virtual memory, which will severely degrade your performance.
Selecting a workspace
When the Workbench is launched, the first thing you see is a dialog that allows you to select where the workspace will be located. Theworkspace is the directory where your work will be stored.If you do not specify otherwise, Eclipse creates the workspace in youruser directory.This workspace directory is used as the default content area for your projectsas well as for holding any required metadata. For shared or multi-workspaceinstalls you must explicitly specify the location for your workspace using thedialog (or via the '-data' command line argument).
Specifying the Java virtual machine
Here is a typical Eclipse command line:
eclipse -vm c:jdk1.5.0_07jrebinjavaw
Tip: It's generally a good idea to explicitly specify which Java VM touse when running Eclipse. This is achieved with the '-vm'command line argument as illustrated above. If you don't use '-vm',Eclipse will look on the O/S path. When you install other Java-based products,they may change your path and could result in a different Java VM being usedwhen you next launch Eclipse.
To create a Windows shortcut to an installed Eclipse:
- Navigate to
eclipse.exein Windows Explorer and use Create Shortcut on the content menu. - Select the shortcut and edit its Properties. In the Target: field append the command line arguments.
Opening this shortcut launches Eclipse. (You can drag the shortcut to the Windows Desktop if you want to keep it in easy reach.)
Mac OS X
On Mac OS X, you start Eclipse by double clicking the Eclipse application. If you need to pass arguments to Eclipse, you'll have to edit the eclipse.ini fileinside the Eclipse application bundle: select the Eclipse application bundle icon while holding down the Control Key.This will present you with a popup menu. Select 'Show Package Contents' in the popup menu.Locate eclipse.ini file in the Contents/MacOS sub-folder and open it with your favorite text editor to edit the command line options.
On MacOS X you can only launch a UI program more than once if you have separatecopies of the program on disk. The reason for this behavior is that every UIapplication on Mac can open multiple documents, so typically there is no needto open a program twice. Since Eclipse cannot open more than one workspace, this means you have to makea copy of the Eclipse install if you want to open more then one workspace atthe same time (bug 139319).
If you need to launch Eclipse from the command line, you can use the symbolic link 'eclipse' in thetop-level eclipse folder. It refers to the eclipse executable inside the application bundle and takesthe same arguments as 'eclipse.exe' on other platforms.
On Mac OS X 10.4 and later, you may notice a slow down when working with significantnumbers of resources if you allow Spotlight to index your workspace. To prevent this, startSystem Preferences, select the Spotlight icon, then the Privacy tab, then click the Add button('+') and find your workspace directory in the dialog that appears.

Shared Install
The startup speed of a shared install can be improved if proper cache information is stored in the shared install area. To achieve this, after unzipping Eclipse distribution, run Eclipse once with the '-initialize' option from an account that has a write access to the install directory.
4.2 Running the e4 demo applications
Loading the example projects
The e4 compatibility platform includes a special menu item for quickly gettingsetup to run the e4 example applications. To use it, do the following:
- Start the e4 compatibility platform.
- Select e4 > Generate e4 Example Project from the top level menu.
- A project called org.eclipse.e4.examples.psf will be created. Select the file e4-examples.psf in this project, and click Import Project Set... in the context menu.
- If prompted for a username/password, enter a username of 'anonymous' and leave the password field blank.
These steps will load the source code of the e4 sample applications into your workspace.To launch and work with the demos, see the following readme sections.
4.2.1 Photo demo application
The e4 photo demo is a simple application that illustrates various concepts of the e4architecture:
- Injection of services in views, making view implementations much simpler
- Alternate workbench layout using a customized e4 workbench model.
- Custom view presentation using CSS
Perform the following to install and run the e4 photo demo. Note that steps 1-6 canbe skipped if the steps for Loading the example projectsabove are followed.
- Start the e4 compatibility platform with an empty workspace directory.
- Select File > Import... and select CVS > Projects from CVS, click Next.
- Enter the e4 repository information. Host: dev.eclipse.org, Repository path: /cvsroot/eclipse, User: anonymous, Connection type: pserver.
- Click Next and select the second option, Use an existing module.
- Drill down as follows: e4 > org.eclipse.e4.ui > examples and select org.eclipse.e4.demo.e4photo. Click Next.
- Important: Do not click Finish just yet. Advance to the last wizard page using Next, then click Refresh Tags. Select R0_9 and click Finish.
- This will check out one project into your workspace. Expand the project in the Package Explorer and open the e4photo.product file.
- Click on the link Launch an Eclipse Application at the bottom left of the e4photo.product file editor.
The e4 photo demo application will come up. Click Create Album or select File > Create Album.The new album location on disk will be printed to your Eclipse console. Just drop a couple (not too many!) of JPEG photos in that directory, then play with the application. Make sure you find a photo with embedded GPS coordinates - when you select it in the Exif view, the Location view will show where the photo was taken using Google Maps. You can find an example photo with GPS coordinates on bug 263898.
Then, have a look at the Application.xmi file to see how the demo application is configured, and/or look at the source files for the individual pieces (views and command handlers).
4.2.2 Contacts demo application
The e4 contacts demo is a simple application that illustrates various concepts of the e4architecture:
- Customizing the look and feel using CSS
- Product branding
- Data binding

Back in the workbench, view and edit the CSSfiles under the org.eclipse.e4.demo.contacts/css folder to experiment with different application styling. Browseand edit the Application.xmi file to customize the application model.
4.2.3 SWT Flex examples
The SWT port for Flex consists of the Adobe Flex environment (the ActionScript compiler), the SWT ActionScript development tools plugins (which provides the tools needed to build, launch and debug Java code in a Flash player) and the Eclipse target environment (the running plugins, the SWT port itself and example code).
Setup Flex environment
- Download and install the Adobe Open Source Flex SDK (available from http://opensource.adobe.com). NOTE: The path where you install the Flex SDK must contain no spaces. This is due to a bug in FCSH.
- Verify that your Flex install works by opening a command prompt, changing to the Flex SDK bin directory, typing 'mxmlc' and hitting Enter. If you get an error message, you will need to add a JAVA_HOME environment variable that points to the home dir or edit the bin/jvm.config file in the Flex SDK.
Setup the Flex tools:
- Update your eclipse.ini file and add another line at the end, -Dflex.sdk=
- Make sure that you are using at least a Java SE 5 JRE to run Eclipse as the ActionScript tools plugin requires it.

4.2.4 Customizing the workbench style
You can experiment with the e4 declarative styling support by manipulating the stylesheetfor the e4 SDK itself. If you've downloaded the e4 SDK, you can find it on disk in:
eclipsepluginsorg.eclipse.e4.ui.examples.legacy.workbench_0.9.0.vSomeBuildDatecsswebby.css
Changes in the style sheet will be picked up in the running platform but you need to tell it that the style sheet changed. To do so, click e4 > Reload Style Sheetin the top level menu.This will re-read the style sheet in and update the UI. Thus you can modify the style sheet on disk and then click the menu to live update the workbench look. You don't need to restart Eclipse.
If you decide to create a new CSS file, you'll need to change the following property in org.eclipse.e4.ui.examples.legacy.workbench/plugin.xml:
<property
name='applicationCSS'
value='platform:/plugin/org.eclipse.e4.ui.examples.legacy.workbench/css/webby.css'>
</property>
4.2.5 Manipulating the workbench model
You can experiment with the e4 modeled workbench by browsing and manipulatingthe model of the compatibility platform itself. When the compatibility platform is running,select e4 > UI Editor from the top level menu. This opens the e4 workbenchmodel editor. You can browse through the structure of the workbench itself in the toppane. Try finding a perspective or view and changing its name, tooltip, or other propertiesin the Basic and Advanced tabs at the bottom. Notice how modelchanges are reflected immediately in the workbench window state underneath!
