[armedbear-devel] installing java dependencies with :mvn ASDF component

The diff from the previous message had several problems.
After fixing the problems one by one I now have working version -
see svn.diff attached (can't submit it as a ticket, because don't know
how to login into the new ABCL Trac).
I must say I now feel how convenient :mvn ASDEF componets are.
I just do (ql:quickload :my-system) and it automatically installs
and loads all the Lisp and Java dependencies (ApachePOI takes 8 .jar files to install).
As for keeping compatibility with old maven. Various approaches possible here.
I would suggest to commit my patch and be compatible with the latest maven
version. If necessary, record a separate ticket to generalize/conditionalize
the :mvn components implementation to make it compatible with both old and new maven.
Maven 3.1.0 release notes, where they describe Aether API change:

> I think I found the reason.
> I am using the latest maven 3.1.0. The Aether API has moved to another packages:
> I have changed contrib/abcl-asdf/maven-embedder.lisp file to use new java class names
> (as in the addached svn.diff), and the error seems gone.
> I continue to work on the Excel improt, will here report if find new information.
