Using the Maven 3 API with Maven 2 Components

Working on a Maven plugin, I was trying to upgrade the Maven API from 2.x to 3.0.4. After the upgrade, the plugin would no longer compile due to an unsatisfied transitive dependency of the maven-archiver used by the plugin: The class org.apache.maven.artifact.DependencyResolutionRequiredException could not be resolved.

The same issue was posted on the Maven Users list, but never answered.

Solution: Add a dependency on maven-core, or on maven-compat which should handle all compatibility issues with Maven 2.
