Hi,
here is a patch attached for an ant target "abcl.mvn.install" which installs abcl- and abcl-contrib-x.y.z.jar into the local maven repository.
It makes it a bit easier to get ABCL into a maven-based project if one is not particularly familiar with maven. There are more options for the plugin[1], but considering the necessary dependencies and the hassle of ant syntax I doubt it's feasible to make more available (except maybe the one to specify a different installation folder).
Best regards, Olof
