Advice migrating jboss AS5 project to AS7

We have a large project ear that contains a .har and a .war, currently built with ant - running on JBoss AS 5. We would like to migrate this application to JBoss AS 7. Much of the AS 7 documentation is Maven-centric. The project does not currently conform to the Maven directory structure conventions and would have to be completely restructured.

Is it worth migrating t开发者_JAVA技巧his application to Maven?

Or would it be quicker to just leave it using ant?

Depends on complexity of the build process.

I would recommend to convert to Maven. AFAIK it's going to be the main build tool for whole JBoss, and many efforts of JBoss as whole are, and will be, Maven centric.
