Fix Version/s: 2.3.1
OK. I have reproduced the issue.
> Ear plugin fails to resolve artifact with null classifier when equivalent,
> classified artifact exists

>
> When resolving ear modules the AbstractEarModule.java class requests a unique
> artifact from the artifact repository using getUniqueArtifact(groupId,
> artifactId, type, classifier). In the case where the classifier is null
> getUniqueArtifact will attempt to find an artifact without considering the
> classifier -- it will match *any* artifact with the same groupId, artifactId,
> and type, regardless of whether the classifier matches (is null). Currently
> the logic in AbstractEarModule does not handle the case where the classifier
> is null: if there is one artifact without a classifier (the one we're looking
> for) and another with a classifier (e.g. a clover jar) the ear module will
> throw an exception at line 104 stating that a classifier is required. This
> means that any build that builds, for example, an instrumented jar, will fail
> to construct an ear.
> This is fixed in the attached patch by explicitly iterating the set of
> artifacts that matches a call to getArtifacts() on the artifact repository
> with just the group, artifact, and type. Ideally this patch would instead be
> made to ArtifactRepository itself to include a search that explicitly matches
> null classifiers.
