EMF Facet/Releng/How to Use
EMF Facet uses the same build system as MoDisco. So, for more explanation about how the build process works, see also MoDisco Releng : How it Works.
What is built?
org.eclipse.emf.facet.all is the feature that is built (defined in buckminster.cspec).
This feature must include all other features that must be built, either directly or indirectly.
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.
The rmap also specifies the update sites from which to retrieve the dependencies.
How to start a build?
45 2-23/3 * * *
- Nightly builds are run every 3 hours everyday, if the EMF Facet SVN changed since the last build.
- Integration builds are started manually
- Only committers in the EMF Facet project, and members of the Callisto-dev group can launch EMF Facet build jobs from Hudson.
- Nightly build : go to https://hudson.eclipse.org/hudson/job/emffacet-nightly/
- Integration build : go to https://hudson.eclipse.org/hudson/job/emffacet-integration/
- 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 download.eclipse.org. For example, a nightly build for version 0.1.0, created on April 21 2011 at 04:13 would be published to:
These builds can then be seen and downloaded from http://www.eclipse.org/modeling/emft/facet/downloads/, 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 0.1.0M6 milestone build:
- First, fetch the build archive to test (from Hudson, or using
- Then, test the build locally
- Then, publish it:
ssh <commiterid>@build.eclipse.org wget https://hudson.eclipse.org/hudson/job/emffacet-integration/lastSuccessfulBuild/artifact/S201103151256.zip unzip S201103151256.zip -d /home/data/httpd/download.eclipse.org/facet/downloads/drops/0.1.0/
- Add a new update site with the new build to the composite:
- Create a new folder with the release number:
- unzip the content:
unzip EMFFacet-Update-0.1.1RC3.zip -d /home/data/httpd/download.eclipse.org/facet/updates/milestones/0.1/SR1_RC3
compositeArtifacts.xmlto add a reference to your newly added update site
- set the value of p2.timestamp to the result of "date +%s000"
- You can enable download stats on the repository by running addDownloadStats.sh on the update site
- Check that the new build appears on .
- Builds can be hidden from this page before a release by modifying
- Update the archive site with the new build:
unzip S201109070430.zip -d /home/data/httpd/archive.eclipse.org/facet/downloads/drops/0.1.1/
/home/data/httpd/archive.eclipse.org/facet/downloads/index.htmlwith a link to the newly added update zip
- Tag the build
If the build must be part of the simultaneous release, you must also:
- Use the B3 Aggregator (or a text editor if the modification is trivial) to update the build model for the aggregator (after checking it out from CVS).
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.
Releases should have a tag like R0_1_0, and milestones should have a tag like S0_1_0M7.
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
or for plug-ins in your workspace:
find $workspaceRoot -name 'build.properties' | while read i; do grep -q about.html "$i" || echo "$i"; done
