Blazej Checinski commented on MENFORCER-248:
--------------------------------------------
I had a look into the logs.
Basing on the previous error: {noformat}MENFORCER-42 is an important
improvement, it seems to have a side-effect: even though dependencies are now
calculated instead of gathered, the artifact is still marked as resolved
afterwards. The assembly-plugin checks if the artifacts is resolved, otherwise
i'll search the local and remote repositories for the files. ( The NPE is
caused by the artifact.getFile() ).{noformat}

What should I upgrade? There is the same issue with assembly 2.6 and enforcer
1.4.1 - which are up to date.

> After upgrading m-e-p from 1.4 to 1.4.1 the maven-assembly-plugin generates
> the following error:
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-assembly-plugin:2.4:single (assemble) on
> project extjars: Execution assemble of goal
> org.apache.maven.plugins:maven-assembly-plugin:2.4:single failed.

> Downgrading to m-e-p 1.4 makes the assembly work again.
> Sample pom & assembly that expose the error attached.
