write developers & contributors into Jar

[Philipp Kraus]

Hello,

I use Maven 3.0 with the developers and contributors inside the pom.xml. I use 
also the manifestEntries with the maven-assembly-plugin to add some flags to 
the Jar manifest file.
I would like to add the developer and contributors list to the Jar, but I don’t 
know in which way I can add a list with name, email, and role types. My idea is 
that I create a comma separated list
list with the data, but how can I create within the pom.xml the correct output 
list? E.g. the pom.xml stores:

<developers>
   <developer>
       <id>myID</id>
       <name>myName</id>
       <email>myName@myDomain</email>
       <roles>
            <role>architect</role>
            <role>developer</role>
      </role>
   </developer>
</developers>

so in the manifest should be a line e.g.

Developers = myName - myName@myDomain - architect / developer,

I have tried to define it with

<manifestEntries>
<Developers>${project.developers}</Developers>
</manifestEntries>

but this writes only the Java object items to the entry. How can I create a 
loop / xquery within the pom.xml to iterate over the developer items?

Thanks

Phil
