This is my cheat sheet for doing a release.
mvn release:clean release:prepare release:perform
Head over to http://oss.sonatype.org/ and do the release.
git checkout master
git merge <tag>
git push origin
git checkout develop
mvn -f varlink-idl/pom.xml tycho-versions:set-version -DnewVersion=0.0.0-SNAPSHOT
git checkout <tag>
# prepare and maybe modify site.xml
mvn site:site site:stage
cd target/staging
# upload, upload p2
git checkout develop
