  • generally do a text search for each repository and replace the old version with new version if appropriate

• If possible: Change versions to 0.0.0 so the newest version in the repository is used

    • Hamcrest

• Update tycho-pomless version, if newer compatible version is available (Link)
  • .mvn/extensions.xml <artifactId>tycho-pomless</artifactId>
