Description

If an InterruptedException occurs in DefaultArtifactResolver.resolveTransitively, it is caught and an ArtifactResolutionException is thrown where the Artifact parameter is null (line 350):
throw new ArtifactResolutionException( "Resolution interrupted", null, e );

Unfortunately, AbstractArtifactResolutionException tries to access properties from that null-Artifact...

The error output is therefore hiding the actual problem:
java.lang.NullPointerException
