Yep - you can check this out: http://svn.apache.org/viewcvs.cgi/*checkout*/maven/components/trunk/maven-artifact-ant/src/main/assembly/dep.xml?rev=192966&content-type=text%2Fplain If you change unpack to false, this is probably close to what you want. I will write some docs on the assembly plugin tonight. You cannot currently change the manifest from the assembly plugin, however - you would need to write your own completely and include it in the list of files in the descriptor to place in META-INF. > > P.S. - On a side note, I've found Maven to be a phenomenally powerful > product that WILL have an immediate impact on the quality of software from > our community.

RE: M2 - Dependent Jars for EJB
Here's the basic gist of what I'm after: Since our EJBs are course-grained, we pass and return value objects in our signature methods... for example, let's take an EJB and call it "ObjectLookup", which has the following method: public Thingy getThingy(ThingyIdentifier id); Now, of course, I would need the jar that defines a "Thingy" (let's call it "thingy.jar") as a dependency when I compile these interfaces, so I add it as a dependency with "compile" scope and it compiles just fine. Now is where it gets interesting though... As I understand it, EJBs are supposed to be stand-alone components, so wherever the ObjectLookup EJB jar gets deployed to, it has to have a "thingy.jar" INSIDE the ObjectLookup EJB jar (as well as a corresponding Manifest.mf classpath entry inside the ObjectLookup EJB jar) so that the container fully understands the EJB component (otherwise the ejb-compile fails). So... I guess I'd be interested in hearing your thoughts as to what the best way of accomplishing this is. The assembly task sounds like the best option... how would I implement this using that task? What hook would I need to use to modify/manually include the Manifest.mf? P.S. - On a side note, I've found Maven to be a phenomenally powerful product that WILL have an immediate impact on the quality of software from our community.

You can actually use the assembly plugin to do this now (though no classpath line). It is uncommon for people to do this as class-path generally doesn't work with jars in a jar.

RE: M2 - Dependent Jars for EJB
First... many thanks for the response! It's so tough to find good examples with this product since it's so new. I tried your example... here's my pom.xml entry: org.apache.maven.plugins maven-ejb-plugin true Of course, nothing different happens when I generate the jar, so I'm guessing that this functionality isn't implemented yet. I'm not entirely sure this will suit my needs anyway... our team uses course-grained EJBs and I need the server-side EJB jar to include some libraries in it (and add the necessary "Classpath" entries in the Manifest.mf). This completely baffles me that no one has had a need to include a jar inside of a jar. I know of the "uberjar" in Maven 1.0, but that's not really what I need either (don't need the bootstrap-code/runnable-jar features). The best technique I've come up with is to painstakingly use the required jars as in the pom.xml... which is an embarrassing hack to which I'm trying to find a better technique. M2 users of the world! Come to my rescue!

Re: M2 - Dependent Jars for EJB
I maybe wrong but I think for the client jars to be included in the ejb jar, you should configure your ejb plugin to do so like: org.apache.maven.plugins maven-plugin-parent true By default, is false.
