This page provides instructions for building the Eclipse Platform using preferred technologies identified as part of the CBI initiative.
Free HDD space
- ~25GB is recommended.
Oracle Java 1.6 or higher
- Oracle 1.6 JDK needs to be on PATH (OpenJDK also works and is becoming officially supported on Red Hat Enterprise Linux for Kepler. See plan).
- Verify correct version of java is used
- set JAVA_HOME to point to your JDK
Some of the inner build callouts, like the SWT fragment build, depend on having an Oracle JVM.
- Download from http://maven.apache.org/download.html or use your Linux distribution provided version (whether it works depends on the distribution).
- make sure mvn is available in your PATH
- You can install Git using your distro's package manager.
Using Maven on Ubuntu
The Maven included in Ubuntu sometimes has issues. See Bug report. If you face such issues, install Maven from the Maven Homepage.
Using Maven on Fedora
Maven package included in Fedora is working without a problem and is used to build the Eclipse Platform package shipped with Fedora.
- Download from http://code.google.com/p/git-osx-installer/
- Install using the downloaded DMG file
- Download Git for Windows from http://msysgit.github.com/
- Install using the downloaded exe file
- We recommend using the "Git Bash" application provided by Git for Windows as your commandline shell throughout the build
Important: Per Bug 376400 we discovered that msysgit has a max character limit somewhere around 256 which causes cloning files with a path longer than that to fail
Workaround: Put your repo in the root of a drive and give it a short name. For example: C:\z
cd c: git clone -b R4_2_maintenance --recurse-submodules \ git://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.git \ z
Note: The final "z" parameter at the end of the command is important as tells git to checkout the repository and rename it to "z". This reduces the path length of the repository to be short enough to workaround Bug 376400.
Build environment setup
Note: Unless otherwise stated, these instructions apply to Linux, MacOSX, and Windows platforms
review maven settings.xml
To avoid getting hit by bug 365727 and to make sure your local environment configuration does not interfere with CBI build, make sure build user account does not have maven settings.xml
igor@desktop:~$ ls -l ~/.m2/settings.xml ls: cannot access /home/igor/.m2/settings.xml: No such file or directory
On Windows XP this is located in:
C:\Documents and Settings\your_user\.m2\settings.xml File should not exist, if it does delete it.
On Windows 7 this is located in:
C:\Users\your_user\.m2\settings.xml File should not exist, if it does delete it.
give maven JVM more ram
If your using Windows:
Note: Unless otherwise stated, these instructions apply to Linux, MacOSX, and Windows platforms
We're currently working on the R4_2_maintenance and R3_8_maintenance branches. When we're confident in them, we'll merge the changes into master.
A script that captures the steps is available in build.sh
cloning platform source tree
Replace R4_2_maintenance with the branch you'd like to checkout.
Clone the repository and checkout the branch:
git clone -b R4_2_maintenance --recurse-submodules \ git://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.git
To update this clone and all submodules:
git fetch origin git merge origin/R4_2_maintenance git pull --recurse-submodules git submodule update
If you want to switch from another branch to this one, replace git merge origin/R4_2_maintenance with:
git checkout -b R4_2_maintenance origin/R4_2_maintenance
Running the build
mvn -f eclipse-parent/pom.xml clean install mvn -f maven-cbi-plugin/pom.xml clean install
Once the parent and the plugin are installed in the local repo, you can run the build from the aggregator root:
mvn clean install -Pno-bree-libs -Dmaven.test.skip=true
NOTE: If you build multiple streams on the same system, you'll want to add -Dmaven.repo.local=/some/directory/somewhere to the end of the 3 mvn commands to avoid collisions (Using a different local repo for each stream). Most casual developers won't be affected.
- On Windows use -Dmaven.repo.local=C:\path\to\somewhere
Once the build finishes, the following artifacts are created.
Packaged SDK zip files are located in your eclipse.platform.releng.aggregator directory under
Packaged JUnit Plugin Tests and Automated Testing Framework
Cleaning the build repo
To completely clean a build repo (before a new build or before updating the aggregator and submodules):
git submodule foreach git clean -f -d git submodule foreach git reset --hard HEAD git clean -f -d git reset --hard HEAD
Using BREE Libs
BREE libs can be used to build using the same BREE as what is used on build.eclipse.org. You will first need to download and install the ee.zip attached to Bug 386649 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=386649) and follow the instructions in the description of the bug.
Once setup you can inform the build to use it by passing -Pbree-libs instead of -Pno-bree-libson the mvn build command.
Pack200 & Signing
Pack200 & Signing is supported when built using build.eclipse.org and is disabled by default.
- Install eclipse-jarsigner-plugin to local maven repository used by the build (i.e. /var/tmp/lts/R4_localrepo).
- Run the build with -Peclipse-sign parameter.
Eclipse Jarsigner can be built from: http://git.eclipse.org/c/cbi/org.eclipse.cbi.maven.plugins.git
git clone -n git://git.eclipse.org/gitroot/cbi/org.eclipse.cbi.maven.plugins.git cd org.eclipse.cbi.maven.plugins git checkout eclipse-jarsigner-plugin-1.0.1 mvn -f eclipse-jarsigner-plugin/pom.xml \ clean install
Optionally, you can pass -Dnative= parameter with one of the following options to compile the natives for the specified native.
- cocoa.macosx.x86 - cocoa.macosx.x86_64 - gtk.linux.x86 - gtk.linux.x86_64 - win32.win32.x86 - win32.win32.x86_64 - win32.wce_ppc.arm
mvn clean install \ -Dmaven.test.skip=true -Dnative=gtk.linux.x86_64
running the tests
Copy the junit tests and the CBI SDK (pick the one for your platform) that was built to a testing directory. Also unzip the junit tests.
mkdir -p /var/tmp/lts/R3_platform-tests cp eclipse.platform.tychoeclipsebuilder/sdk/target/products/org.eclipse.sdk.ide-linux.gtk.x86_64.tar.gz /var/tmp/lts/R3_platform-tests cp eclipse.platform.tychoecilpsebuilder/eclipse-junit-tests/target/eclipse-junit-tests-bundle.zip /var/tmp/lts/R3_platform-tests cd /var/tmp/lts/R3_platform-tests unzip eclipse-junit-tests-bundle.zip
Modify the file equinoxp2tests.properties to point to the CBI built repository. (This example uses /home/user/R3_platform-aggregator as the CBI platform root)
Note down the org.eclipse.equinox.p2.reconciler.tests.platform.archive.linux-x86_64= file name for your architecture. (In this example linux x86_64)
Rename your org.eclipse.sdk.ide-linux.gtk.x86_64.tar.gz you copied earlier to match the name you jotted down.
mv org.eclipse.sdk.ide-linux.gtk.x86_64.tar.gz eclipse-platform-201204121421-linux-gtk-x86_64.tar.gz
Copy your eclipse-platform to eclipse SDK
cp eclipse-platform-201204121421-linux-gtk-x86_64.tar.gz eclipse-SDK-201204121421-linux-gtk-x86_64.tar.gz
Download a copy of the latest released Eclipse Classic from http://www.eclipse.org/downloads/.
Copy the Eclipse Classic SDK to eclipse-platform
cp eclipse-SDK-3.7.2-linux-gtk-x86_64.tar.gz eclipse-platform-3.7.2-linux-gtk-x86_64.tar.gz
You should now have 4 copies of the platform, 2 from the latest released and 2 from the CBI build.
eclipse-SDK-3.7.2-linux-gtk-x86_64.tar.gz eclipse-platform-3.7.2-linux-gtk-x86_64.tar.gz eclipse-platform-201204121421-linux-gtk-x86_64.tar.gz eclipse-SDK-201204121421-linux-gtk-x86_64.tar.gz
Unzip the CBI platform
tar zxvf eclipse-platform-201204121421-linux-gtk-x86_64.tar.gz
Run the tests
./runtests -os linux -ws gtk -arch x86_64
Bug 384482 - Apple JVM renamed rt.jar to classes.jar causing CBI Platform build issues
Apple JVM renamed rt.jar to classes.jar causing the CBI Platform build to fail when building on macosx. Running the build a 2nd time after the failure however produces a working build. It isn't ideal to have the user run the build twice though.
A workaround for this issue is to create a symbolic link for classes.jar to rt.jar.
cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib sudo ln -s ../../Classes/classes.jar rt.jar
Submitting for aggregator builds (Proposal)
In PDE build the features specify what plugins to build and the map files specify where to get the plugin projects and which version to check out.
In the CBI build the pom.xml files and the directory structure specify what plugins to build and the aggregator git repo specifies which checkout is the build input by capturing the commit for each component repo as a submodule entry.
The manual process for submitting Platform UI for a build involves updating the submodule in the aggregator:
# starting in eclipse.platform.releng.aggregator cd eclipse.platform.ui git checkout R4_2_maintenance git pull cd .. git status
The status should look something like:
# On branch R4_2_maintenance # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # (commit or discard the untracked or modified content in submodules) # # modified: eclipse.platform.ui (new commits) #
To pull in the new commits, just add the repo:
git add eclipse.platform.ui git commit git push origin HEAD
These steps can be driven by a file similar to repositories.txt and done in place of the auto-tagging step at the beginning of the build.
