ctags

In .vimrc:
autocmd FileType java set tags=tags,~/.tags_java

Generate Java ctags by finding /usr/lib/jvm/java-7-oracle/src.zip and unpacking to /usr/src/java-7-oracle and then ctags -R --language-force=java -f.tags_java /usr/src/java-7-oracle

Debugging

With Maven you can use mvnDebug or mvn -Dmaven.surefire.debug which will kindly wait for a debugger to attach (jdb -attach 8000 or 5005, etc). Followed by stop at some.package.spec.Class:<linenumber> and then run. Unit tests (ie the test goal) don't seem to respect jdb when using mvnDebug so the alternative is recommended. It may be more useful for other goals. Don't forget to give jdb a good sourcepath as -sourcepath . from your root doesn't seem to cut it. Try to use a src folder.
