No, though that would be a good blog post. We tried to make multi-module maven work for a while, eventually gave up and wrote some scripts that would convert maven to bazel, using many assumptions that applied only to our particular case. We did the cutover in one day but kept maven around for a couple weeks in case we decided to bail on bazel. It worked out; we even found CircleCI works great. I would say the weak link in the bazel ecosystem is the IntelliJ plugin, which is very functional but also very slow.
