-----------------------------------------------------------------
This seems to be another regression of FELIX-6493. [~HannesWellmann] Can you
have a look? This seems to be triggered when the goal is executed when the
parent hierarchy is being traversed
(https://github.com/apache/felix-dev/blob/28b4c77883b8dbdea06e723dc4e5a3eba7393f34/tools/maven-bundle-plugin/src/main/java/org/apache/felix/bundleplugin/ManifestPlugin.java#L436)
and {{project.getFile()}} returns null.

This seems to be another regression of FELIX-6493. [~HannesWellmann] Can you
have a look? This seems to be triggered when the goal is executed when the
artifact has not yet been attached
(https://github.com/apache/felix-dev/blob/28b4c77883b8dbdea06e723dc4e5a3eba7393f34/tools/maven-bundle-plugin/src/main/java/org/apache/felix/bundleplugin/ManifestPlugin.java#L436),
i.e. {{project.getFile()}} returns null.
