Thanks all, I've got it working now :) Alan
-----Original Message----- From: Michael Dick [mailto:[email protected]] Sent: 18 May 2009 22:45 To: [email protected] Subject: Re: Building in Eclipse I think this is a variation on the "one big project" approach that some people seem to like. I prefer to build each module as a separate compilable unit (ie the way maven does). The benefit is that when I break access rules (ie try to reference something from openjpa-jdbc in openjpa-kernel) my eclipse build failes before I do a real maven build.. It's all personal preference though and YMMV.. IDEA and NetBeans have built in maven support that (I'm told) works pretty nice. I can't give up Eclipse's incremental compiles though. FWIW the steps for the multiple module approach are on our wiki at [1]. If you're willing to start from scratch that might be a good place to do. Donald's done a great job of updating that section of the wiki to keep it up to date (thanks Donald).
