would be the same, because both with maven or ant must be generated for each artifact

(this file properties are unusable because some modules are not importable,
e.g.  
gradle-jetty use jetty 6.x
gradle-sonar use https://bugzilla.redhat.com/show_bug.cgi?id=848096 == 3.2 and not newer release)

solved ... i think ... see http://pkgs.fedoraproject.org/cgit/gradle.git/tree/gradle-1.7-asm3.patch?h=experimental
