<div>So I have some POM files almost working, but without a repository with JDOM 1.1.1 it won't be easy. The other thing that I notice from the POM files is that there are currently resources under src/main/java... and src/main/test</div>
<div><br></div><div>Would it be possible to move them to src/main/resources and src/test/resources? This would simplify the maven POMs and make them more readable to everyone. I'm guessing there would be some ant build script changes there...</div>

That's why it was designed in the first place. It's aim is to be as portable as possible. Dependencies are stored outside, and custom repositories can be defined as part of the poms if they are not on Maven's Central repository. Nexus is a free repository for that kind of thing so we can easily set one up on the crosswire server. The instructions for building STEP come in 2 steps (spot the play on words!): </div>

<div><br></div><div>D) Setting up a repository</div><div>Yes that is easy to do. And the best way to do it really, would be to have a crosswire repository on <a href="http://crosswire.org/" target="_blank">crosswire.org</a> where releases and snaphots (nightly builds) are stored. Then mirror the releases to Central (or some other popular repository). Nexus comes as an HTTP server as well. So maybe that would help the translators in your question above? At the moment, I'd like to build STEP against JSword snapshots ideally, because I'd like to know that if I submit a patch to JSword, I can confidently rely on the next snapshot to have my fix in. When I release however, I will release against the released versions. Perhaps when I'm ready to release I could ask for a minor point JSword release?</div>

However, it's quite a big decision to move from one to the other and I don't think both work together very well, as one has to maintain 2 builds (which as we've seen can be difficult - the maven currently being broken). Clearly lots of people use Ant and aren't familiar with Maven (I was like that). Can I suggest a compromise:</div>

<div><br></div><div>The main idea behind maven is that like Ivy is can do your dependency management. The POM file describes the project, the type of file associated with it (jar, war, sources, etc.) and all its dependencies. I think the above link would be a good compromise.</div>
<div><br></div><div>It tries to generate the POM from what it knows of the Ant build, and then deploy to a repository. Would someone be willing to see if they can get that working in the ant build (i'm not very familiar with that).
