Releasing Tycho

This page describes the steps necessary to create releases of the Tycho project.

  • Prepare the Tycho/Release Notes which should provide a quick overview of new features and bug fixes
  • Steps below apply to both tycho and tycho-extras git repositories as these should normally be released together and with the same version
  • Update versions using
    mvn org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=...
  • Commit version change, create a git tag tycho-<VERSION> on this commit and create a new remote branch tycho-MAJOR.MINOR.x based on this commit in git
  • Update versions (same as above) to next -SNAPSHOT development version and push commit to master branch
  • Make sure you have everything setup (GPG installed!) for deploying to the Nexus OSS repository, see guide
  • Add your credentials for server <OSS_ID> in ~/.m2/settings.xml
  • Sync to release commit and deploy to nexus staging repository:
    mvn clean deploy -Prelease -DforgeReleaseId=<OSS_ID> -DforgeReleaseUrl=https://oss.sonatype.org/service/local/staging/deploy/maven2/
  • Close the staging repository and announce the temporary stage URL on tycho-user@eclipse.org:
    Subject: please test staged tycho <VERSION>

    Please help testing the staged tycho release <VERSION>.
    The staging repository URL is [1]. For details see release notes[2].

    We plan to promote this release in one week unless major regressions are found.

    Regards,
    Tycho team
