Hi Tibor,

Bullet 4: Remove maven-compat (or give it the test-scope if it is required by the maven-plugin-testing-harness)

Now I think you're at a state where Maven2 classes must be replaced with Maven3 solutions.

Hi Tibor,

so this is not how it should be done.
Compat contains classes which Maven2 classes which have been replaced by
Maven3 or are not used anymore.
Only plugins which need to stay compatible with Maven2 should include this
dependency.

I'll update the page, because we've decided to change the version to
3.0-SNAPSHOT

And regarding your other message: see the third bullet when using
maven-plugin-testing-harness. Use version 2.1 if you want to ensure that
the tests are Maven 3.0 compatible.

If you need help, just let me know. By now I can recognize most of the
migration issues :)

thanks,
Robert

I missing this import in MOJO after migrating plugin to 3.0

The doc [1] says that maven-artifact-transfer should be used but it does
not have yet a release version, or?

<dependency>
  <groupId>org.apache.maven.shared</groupId>
  <artifactId>maven-artifact-transfer</artifactId>
