The MoDisco project is built using Buckminster, with this releng project. (for old Athena build, see this page)

For more explanation about how the build process works, see also How it Works?.

What is built?

org.eclipse.gmt.modisco.all is the feature that is built (defined in buckminster.cspec). This feature must include all other features that must be built.

The releng project contains a Buckminster rmap, which specifies how to get the plugins and features that are to be built. For each plugin or feature, the map defines its location on a version control system (CVS, SVN), and the version that must be used.

How to start a build?


  • Nightly builds are run every 6 hours everyday, at 02:10, 08:10, 14:10 and 20:10 EST, if the MoDisco SVN changed since the last build.
  • Integration builds are started manually.



  • In Hudson, click on Build Now, change the build parameters as needed (see #Build parameters), and click on Build.
  • You can then click on the job name in the Build History section in the left column, and then on Console Output, to follow build progress in real time.

How to publish a build?


Successful Nightly and Integration builds are automatically published to For example, a nightly build for version 0.8.0, created on October 6 2009 at 11:54 EST would be published to:

These builds can then be seen and downloaded from, where additional information is available (test results, build log).


Stable, Maintenance and Release builds are not automatically published. They should be first tested internally before publishing. For example, to publish the 0.8.0M2 milestone build:

  • First, fetch the build archive to test (from Hudson, or using wget or scp for example).
  • Then, test the build locally
  • Then, publish it:
ssh <commiterid>
unzip -d /home/data/httpd/
  • Finally, for a milestone, update the update site with the new build:
rm -rf /home/data/httpd/*
unzip -d /home/data/httpd/
  • For a release:
    • Create a new folder with the release number under /home/data/httpd/
    • update compositeContent.xml and compositeArtifacts.xml to add a reference to your newly added release
  • You can enable download stats on the repository by running addDownloadStats.shon the update site
  • Check that the new build appears on
  • Builds can be hidden from this page before a release by modifying downloads-scripts.php in www/MoDisco on
  • Update the archive site with the new build:
    • copy the drop folder (eg. "S200910061155") into /home/data/httpd/
    • update /home/data/httpd/ with a link to the newly added update zip

Simultaneous Release

If the build must be part of the simultaneous release, you must also:

Build parameters

Hudson builds expect these parameters:

  • BUILDTYPE : the kind of build, represented by a code letter (see this page):
    • N: Nightly
    • I: Integration
    • M: Maintenance (NOT milestone)
    • S: Stable (for Milestones and Release Candidate builds)
    • R: Release
  • BUILD_ALIAS : the name of the release (0.8.0, 0.9.0M1, etc.); blank for nightly and integration builds
  • SIGN_UPDATE_SITE : whether to sign the update site (takes about an hour on the Eclipse build server); mandatory for releases
  • VERSION : the version being built. Dictates in which folder the build will be placed under the download "drops" folder.
  • PROJRELENGROOT : The path on the SVN (trunk, branch or tag) from which to take the version of the releng project that must be used for this build.

Building locally



To tag a release, use this script:
Releases should have a tag like R0_7_1, and milestones should have a tag like S0_9_0_M2.

Tag names
Since the tag name is used as a bundle qualifier by PDE Build, it should not contain periods. For example, use R0_7_1 instead of v0.7.1

Checking bundles

Check that each bundle contains an about.html file:

for f in $( ls *.jar ); do unzip -t $f | grep -q about.html || echo $f; done
