Play! war command - Is it possible to exclude certain jar from the application /lib folder

Question

I'm trying to automate deployment of a play application as a .war file.

In the end the application will be run on JBOSS AS7. The problem I'm running into right now is that when I deploy the war to JBOSS I get this exception.

I found that if I manually remove the lib/netty-3.2.5.Final.jar file from the war before deploying it to JBOSS the problem goes away.

Now is there a way to do this when I'm generating the war with the play war command? Any information on this would be much appreciated. Thanks

Answer 1

Not that I am aware of simply. The play war command allows you to pass an exclude list, which I have copied the comments from the python file below.

~ To exclude some directories, use the --exclude option and ':'-separator (eg: --exclude .svn:target:logs:tmp).

However, this suggests it will only work for directories.

The command that is executed is package_as_war in framework/pym/utils.py, so you can hack that to specifically delete the file, but obviously this will not be backward compatible if you update your version of Play.
