Slawomir Jaranowski commented on MSHARED-1130:
----------------------------------------------
The root cause is in method of {{PatternIncludesArtifactFilter}}
{code}
private static Artifactoid adapt( final Artifact artifact )
{
requireNonNull( artifact );
return coordinate ->
{
requireNonNull( coordinate );
switch ( coordinate )
{
case GROUP_ID:
return artifact.getGroupId();
case ARTIFACT_ID:
return artifact.getArtifactId();
case BASE_VERSION:
return artifact.getBaseVersion();
case CLASSIFIER:
return artifact.hasClassifier() ? artifact.getClassifier()
: null;
case TYPE:
return artifact.getType();
default:
}
throw new IllegalArgumentException( "unknown coordinate: " +
coordinate );
};
}
{code}
for empty {{Classifier}} null is returned.

> Key: MSHARED-1130
> URL: https://issues.apache.org/jira/browse/MSHARED-1130
> Project: Maven Shared Components
> Issue Type: Bug
> Components: maven-common-artifact-filters
> Affects Versions: maven-common-artifact-filters-3.3.1
> Reporter: Andrzej Jarmoniuk
> Priority: Major
>
> Encountered an NPE from {{PatternIncludesArtifactFilters.match}} if the
> pattern includes wildcards and the artifactoid returns null on any of its
> coordinates.
> In such cases, the {{value}} argument will be null, which will lead to an NPE
> when it's being dereferenced in line 653.
> This led to https://github.com/mojohaus/versions-maven-plugin/issues/673
> In this case, {{token}} was {{JET*-SNAPSHOT}} and {{value}} as returned from
> the artifactoid was null.
