The important change in this commit is in the implementation of
getClassifier()
methods. However, this commit opportunistically refactors the code with a base class shared byDefaultDependency
andDefaultDependencyCoordinate
implementations.Note on build failure
Trying to compile Maven with itself (4.0.0-beta-4-SNAPSHOT) fails with a
NullPointerException
in thePluginsMetadataGenerator
class of the "Maven Compat (deprecated)" module. The issue seems more serious than a missing null check, because according the sanity check at line 137, the plugin is operating on the wrong artifact. However, this issue is not related to this commit. Testing with the commit before this one produces the same result. Building with Maven 3 works fine.https://issues.apache.org/jira/browse/MNG-8197
