I'm trying to create a repository via Maven assembly plugin and used the includeMetadata option. If i use false everything is ok (or just remove completely cause false is the default). If i change it to true i got the following failure:

[ERROR] 
{code}

Created a [github|https://github.com/khmarbaise/assembly-failure] project to reproduce the problem and attached the project which produces the failure.
The assembly-repository is exactly as the assembly-repository-failure except with the difference in the includeMetadata entry in the assembly descriptor.
