Description

The issue is the same as in MDEP-448 but on the unpack-dependencies goal.

It can be resolved by applying the same patch also to the file: org.apache.maven.plugin.dependency.fromDependencies.UnpackDependenciesMojo.java line 98

Note that the problem is the logging when markers are present. To produce a test simply run the configuration below using any dependency with javadocs attachments. The first run is okay the second run fails with NullPointerException from
org.apache.maven.plugin.dependency.fromDependencies.UnpackDependenciesMojo.java line 98
