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

[Anton Vodonosov]

I think I found the reason.

I am using the latest maven 3.1.0. The Aether API has moved to another packages:
org.eclipse.aether.*

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.

Best regards,
- Anton
