Mikael:

1- I've posted about the exact same thing earlier about 8 hours ago on
the same list. You may want to monitor that email thread. The email
was titled "using assembly to repackage a war".

2- as described in my email (and the issue I opened here [1]) I am
hitting an issue using the assembly to package wars. I was told on IRC
#maven that the assembly is not to be used for war packaging, but to
me it's currently the cleanest solution. I will probably investigate
the issue. Feel free to track the issue as well.

3- As Nicolas asked me, you will find below the scripts I am using to
do a simple bundling.

The use case is the following: one war and 2 zips produced. The zip
files contain webstart applications. I want to unzip the zip files in
the correct place in the webapp.

4- Would be happy to know from both Nicolas and you what are your
exact use cases. If fixing the assembly plugin to support war assembly
is not an option, we might need to create a new goal for the war
plugin.

That's pretty simple.
