Ading classpath to jars

Jean-Marc Lavoie Thu, 19 Feb 2004 09:16:26 -0800

From what I have seen, the only way to generate the classpath in a manifest is to generate an EJB jar, wich is an ejb dependency, instead of a jar dependency.

I modiifed the jar plugin script based on the article "Maven magic" to include this feature,

This classpath can be added in a way similar to ejb jars.

The folowwing would inlcude the jar in the manifest classpath

Here is the Jelly script and diff If someone want's to include it in the jar plugin. I include it inline in case the attachment get corrupted/kicked out.

I may have to update war file also, let me know if you want the files

Thanks
