What files do I need to run an Athena build?

In some folder, traditionally called org.eclipse.myproject/releng or org.eclipse.myproject.releng (but really, it can be anything), you need these files:

maps/*.map -- what to build (where to get sources) : can be CVS, SVN, or HTTP (eg., Orbit jars) -- how to build -- what tests to run
build.xml -- boilerplate script for running the build in Eclipse, via commandline, or in Hudson

I also recommend having a .launch file which produces a log of your in-Eclipse build attempts so that when that log scrolls off the Console view, you can see what happened in the file.

And, if you want to make it easier for others to get your source, you can include psfs/*.psf files. Better, use build.steps=map2psf in your to generate .psfs from your map files.

My build complains it can't find java.lang.Object. Seriously, WTF?

First, make sure EVERY plugin you're building has a Bundle-RequiredExecutionEnvironment defined. If not, PDE will thing you're trying to build Java 1.2 or 1.3 code, and your Java 5 annotations will fail to compile.

Next, in your .releng project's file, make sure you've set JAVA_HOME to a valid path, as well as setting a valid path for every Bundle-RequiredExecutionEnvironment ("BREE") defined in your plugins' MANIFEST.MF files. If all your code is set to BREE 1.4, you only need a JAVA14_HOME; if you have a mix, include all that you use, such as JAVA50_HOME or JAVA60_HOME.

Here are the default values for these


See also the PDE/Build documentation on controlling the classpath and source/target levels.

Finally, note that if you're running on a 64-bit OS with a 64-bit Eclipse, you need a 64-bit JVM.

My build fails with a failure in getDependenciesHelper.xml and a Java returned: 13

One of the most likely causes for this is a dependency that was impartially downloaded. You should clear our your tmp downloads directory and try again.

What are buildExtra.xml and testExtra.xml for?

These are optional.

If you have custom runtime requirements which cannot be configured using dependencyURLs or repositoryURLs in your, you can define additional fetching/unpacking steps here, for building or testing respectively.

If you have custom packaging steps (ie., you ship more than the default set of zips) you can also add packaging steps here.

My build fails in the packageTestFramework step. Why?

See answer for ${org.eclipse.test} not found.

${org.eclipse.test} not found? PackageTestFramework step fails w/ Java exit code 13?

1. Include "org.eclipse.test" and "org.eclipse.ant.optional.junit" plugins in your all-in-one tests feature (or to each test feature). This controls what plugins PDE will build.

  download-size="0" install-size="0" version="0.0.0"/>
  download-size="0" install-size="0" version="0.0.0" fragment="true"/>

2. Add these plugins to your map file (or create a new map file). This controls where PDE will find the Eclipse Test Framework (ETF) sources.


Do I still need a test.xml in each of my test plugins?

No. In fact, having one there may cause some of your tests to fail. Omit this file and one will be generated for you from this template.

How do I build source features / plugins?

Three touchpoints are required:

1. In your .releng project's, set:


2. In your runtime feature, define templates for features/plugins to be generated:


3. In your SDK or "all-in-one" feature, define how to generate the feature / plugin:


See also PDE Build > Generating Source Features and Plug-ins.

What information do I need to provide to get a new job added to Hudson?

To get added to Hudson, see Build In Hudson.

How do I create Team Project Sets as part of the build?

Add the map2psf target to your file. This will create a psf directory in your releng project, that contains the PSFs.

When I check out org.eclipse.releng.basebuilder, it doesn't compile.

See Common Build Infrastructure/Getting Started/FAQ/Basebuilder.

My build used to work but now headless UI tests are broken!

Add the following line to in your releng project:

The lastSuccess symbolic link disappeared on the file system! How do I access my lastSuccessful build.

content inaccurate
since bug 302170 is fixed, you can point out directly your hudson workspace to find the last build.

See bug 302170.

Previous tip :

If you need to access this using the promotion script, then you need to create a promotion script similar to the following:


# where you will unzip build

# where you will have your promotion logs

# where is your releng job, ie /opt/users/hudsonbuild/.hudson/jobs/cbi-emf-eef-0.7-nightly/workspace/build/org.eclipse.eef.releng

# this script log

# Ant installation

rm -f $logFile
echo "[`date +%Y/%m/%d\ %H:%M`]: getting last successful build" >> $logFile
mkdir -p $BUILD_LOC
rm -f $BUILD_LOC/
rm -rf $BUILD_LOC/build
wget --no-check-certificate "*zip*/" -o $logFile
if [ ! -f ]; then echo " (from Hudson) not found" >> $logFile; exit -2; fi
unzip >> $logFile
echo "[`date +%Y/%m/%d\ %H:%M`]: publishing nightly build ..." >> $logFile
mkdir -p $PROMO_LOGS_DIR
$ANT -f $RELENG_DIR/promote.xml$RELENG_DIR/ 2>/dev/null 1> $PROMO_LOGS_DIR/cbi-emf-eef-promo-N.txt

This uses the REST API provided by Hudson to access to the necessary files from the last successful build.

You must also modify your file to use the unzipped build file that resides in the BUILD_LOC folder instead of the lastSuccessful URL.

How do I publish my builds from Hudson to

See Common_Build_Infrastructure/Publishing.

How do I contribute to Helios?

There is currently no automated way to contribute to Helios.

See Helios/Contributing to Helios Build for the manual method and bug 287013 for the work-in-progress for generating a .build file.
