Extra files do not bother me, and I even compare them sometimes. The contents of src/dist/build/distributions is never scanned for the list of files to publish, and I see no reason to clean it every time. You can execute gw clean (or ./gradlew :src:dist:clean) if you want before the release. You can use gradlew :src:dist:clean prepareVote ... as well. Vladimir
