Apache Maven 3.5.0 Release

The Apache Maven team would like to announce the release of Apache Maven 3.5.0.

You can download the appropriate sources etc. from the download page.

Notable changes

  • ANSI colors added to the console output
  • Fix various bugs in mvn scripts regarding spaces, quotations, special characters, etc. also in combination with .mvn/ -files
  • Switch from Eclipse Aether to Maven Artifact Resolver

What happened to Maven 3.4.0?

After Maven 3.3.9 was released, the Eclipse Aether project was retired and the code base was migrated to the Apache Maven project.

The original goal for the 3.4.0 release was to replace Aether with the exact same code after migration to the Apache Maven project and then proceed with bug fixes to the resolver code as well as other areas of Maven.

The migration of the code between the two foundations took longer than expected and as a result there were other changes committed to Maven core that were outside the scope of intent for 3.4.0.

In order to refocus on the original intent for 3.4.0, the decision was taken to revert the Maven core history to the point of the 3.3.9 release and merge in the desired changes one at a time.

Because there had been a lot of communication about different features being delivered and bugs fixed in Maven 3.4.0 and the new history may not contain them in the first release, the decision was taken to forever burn the 3.4.x release line.

More detail on this decision can be read in the mailing list archive1.
