Hello,
I have the same problem on my macbook.
If you take a look at the assemble-plugin.xml you will see this:
...
<fileSets>
<fileSet>
<directory>/</directory>
<includes>
<include>plugin.xml</include>
<include>META-INF/</include>
</includes>
<outputDirectory>/</outputDirectory>
</fileSet>
</fileSets>
...
The problem is that "directory" must point to the current directory
"./" and not to the root directory "/".
Maven simply do not finds the files. I guess this fails on linux too.
I think this should break the build or at least print a warning.
