I'm trying to build jboss 4 from the source (I want to build a test case for a specific ejb3 problem and I'd like to use as much of what already exists as possible). I've followed the instructions at: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossBuild These boil down to using cvs to do a checkout of: cvs co -r Branch_4_0 jboss-4.0.x then going to the build directory and running build - I get that far no problem. The problem is that the build task finishes with an error: jboss-4.0.x\thirdparty\jboss\aop\component-info.xml:1: Content is not allowed in prolog. Which, if coming from an xml processor is not unreasonable as the contents of that file is: a352a1e9b02f9d56fecf3c672f741583 ./jboss/aop/1.5.1.snapshot/component-info.xml which is not very xmlish at all... Its been a long couple of weeks so its perfectly possible that I've missed something really obvious... Anyone has any idea what I need to do to get the build working?
