You need ensure the
is in the maven repo which your FUSE ESB can access, that said, it should be in your local maven repo, or if it's in some remote maven repo,
you need ensure the remote maven repo url is in the etc/org.ops4j.pax.url.mvn.cfg, defined by org.ops4j.pax.url.mvn.repositories property.
I think the easiest way is uncompressing the src.zip and run "mvn install" inside the src directory.
maven will install all the artifacts for you and you don't need to figure out the remote maven repo url any more.
