Missing component annotations for maven3 and maven31 dependency collectors

org.apache.maven.shared.transfer.dependencies.collect.internal.Maven30DependencyCollector and org.apache.maven.shared.transfer.dependencies.collect.internal.Maven31DependencyCollector

do not have @Component annotations so they cannot be looked up by Plexus.

This appears in maven-dependency-plugin list-repositories integration tests when you try to update artifact-transfer past 0.11.0 to 0.12.0.

This might be fixed at head since it looks like that no longer uses Plexus to find the Maven31DependencyCollector and Maven30DependencyCollector classes.
