[dna-users] Building DNA Question

[Randall Hauch]

Hi, Ben.

Either list would be fine.  The versions you mention all look to be  
okay, but it's obviously not working.  I presume that you're getting  
this exception on the first project (DNA Common).  If not, please  
reply with the project on which it's failing.

I do have a couple of suggestions.  First things first, have you  
looked at the http://wiki.jboss.org/wiki/Maven wiki page, which talks  
about how to use Maven on the JBoss projects.  There's probably more  
detail there than you need, but it's a starting point.  That page also  
links to http://wiki.jboss.org/wiki/MavenSettings, which talks about  
making sure you're pointing to the JBoss Maven 2 repository.  That's  
been the most important thing.

What is the Maven command you're running?  I usually run "mvn clean  
install" in the top-level directory (i.e., in "trunk").

Another thing to try might be to temporarily move your "~/.m2/ 
repository" folder and try build everything from the beginning.  This  
would check whether you already have incompatible libraries in your  
local repository.  Just remember to move your "repository" folder back  
when you're finished.

I've not yet tried building with JDK 6, so I'll try to do that.  Also,  
I also haven't heard whether anyone has built DNA on Windows (Macs and  
Linux machines, yes), so I'll try to dig up a Windows machine and give  
it a whirl.  From your message, I presume you have both JDK 5 and 6  
installed?  Do you have cygwin installed?

Best regards,

Randall
