Eclipse Build Available RSS Feeds

Recent changes to this document

Sample Feeds

Support For Jar Signing

So that we can identify which projects' builds are signed, the <build/> node can take an attribute for jars, thus:

<feed xmlns="">

I'm thinking of 5 status codes, assuming the current jar signing process continues as proposed:

  • NONE (or "") - no status available or not participating
  • UNSIGNED - no jar signage available or done yet
  • SIGNREADY - jars promoted to, ready for signing
  • BUILDREADY - signed on, ready to be collected and bundled as zips and copied to UM site
  • SIGNED - signed & bundled on download page and on UM site

Support For Build Type

So that we can identify what type of build a given entry is, these values can be specified for a type attribute:

  • N : Nightly
  • I : Integration
  • M : Maintenance
  • S : Stable (Milestone or Release Candidate)
  • R : Release
  • MC : Maintenance-Callisto
  • SC : Stable-Callisto
  • RC : Release-Callisto

If the property buildType is not specified, the ant task will attempt to guess the build type based on the buildID, like this:

 public void setBuildType(String buildType) 
   if (!isNullString(buildType)) 
     this.buildType = buildType;
     this.buildType = buildID.replaceAll("[^NIMSR]", NS); //$NON-NLS-1$
     if (this.buildType.length()>1) 
       this.buildType=this.buildType.substring(0, 1);

Support For Callisto Status

So that we can identify which projects' have been posted to Callisto, there's an attribute on the <build/> node, thus:


Status codes here could be:

Code Purpose/Description
NONE (or "") not part of Callisto or unknown status
BUILDCOMPLETE Have you finished your RC1 bits?
2006-05-02T20:50:00Z When do you expect to finish them?
TPTP If you're waiting for another project, which one(s)?
UMSITEREADY Have you placed those bits in your update site?
CALLISTOSITEREADY Have you updated the features.xml file in the Callisto CVS directory?
COMPLETE Are you ready for RC1 to be declared?

Where To Publish

In order to ensure that your feed data is as current as your promoted bits, it's recommended that you publish your feed to the same place you publish your zips/jars. For the EMF example, this is, and the CVS archived version of the file is /cvsroot/org.eclipse/www/emf/feeds/builds.xml.

If you plan to publish more than one feed or your project contains subprojects which are built or published separately, it's recommended that you name your feeds with the subproject, branch, and type, eg:

Working Examples

These are working examples implemented and in use, based on the samples provided in


Crontab scripts:

# EMF M builds (2.2.1)

# M build every Thu (4); runs as web user, www-data
0 0 * * 4 sudo -u www-data /home/www-data/emf-build/scripts/ -proj emf -buildType M \
 -tagBuild true -branchCVS HEAD -noperf -runJDK14Tests -runJDK50Tests -runOldTests > \
 $HOME/cron_logs/ 2>&1

# promote M build + update feed (among other things)
0 1 * * 4 /home/www-data/emf-build/scripts/ -proj emf -branch 2.2.1 -type M \
  -user nickb -userIES nboldt -announce > $HOME/cron_logs/ 2>&1


Crontab scripts:

# UML2 M builds (2.0.1)

# respond to emf feed change; runs as web user, www-data
0 2,3,4 * * 4   cd /home/www-data/emf-build/scripts/ && sudo -u www-data \
 /home/www-data/emf-build/scripts/ -proj uml2 -branchCVS R2_0_maintenance > \
 $HOME/cron_logs/ 2>&1

# promote M build + update feed :: currently not automated (by choice)

If a change is seen in the feed, run the respondToFeedChanged target in feedWatch.xml, which has been customized to update dependencies then run a build:

<target name="spawnBuild">
  <echo message="Spawn new build:"/>
  <echo message="/home/www-data/emf-build/scripts/ -proj uml2 ${buildType} ${buildAlias} -branchCVS ${branchCVS} ${runOptions} -URL '${feedWatchAction.TheValue.2}/${feedWatchAction.TheValue.1}' -URL '${feedWatchAction.TheValue.3}'"/>
  <exec spawn="true" executable="bash" resolveexecutable="true">
    <arg line="/home/www-data/emf-build/scripts/ -proj uml2 ${buildType} ${buildAlias} -branchCVS ${branchCVS} ${runOptions} -URL '${feedWatchAction.TheValue.2}/${feedWatchAction.TheValue.1}' -URL '${feedWatchAction.TheValue.3}'"/>

Latest Code

The latest code can be found in CVS, currently in the releng_test branch:

The latest XML Schema is here:

Additionally, zips are available here (but are NOT as recent as what's in CVS):

  • Shell & Ant tasks to create, update, query & publish feeds (CVS, SCP)
  • Shell & Ant tasks to respond to feed changes (eg., sending an email, firing another ant task, launching a shell process with <exec>)
  • Ant task (and shell wrapper) to validate a feed against the latest schema
