No repositories searched by default

[pgr0ss]

The commit to enable custom repositories (https://github.com/bazelbuild/migration-tooling/commit/a5e687403ec59db52383a2c0996003e5ad18b6cf) seems to have caused this project to use no repositories by default. Can we return to using default repositories if no repositories are specified?

Is this project still active? It seems like this bug would break most people trying to use it?

[pgr0ss]

Bump. Should we avoid this project now? What's the future of maven dependencies in bazel?

@pgr0ss

I don't think it is. During the November Bazel conference, it was decided that the official maven story would be handled with bazel-deps. Unfortunately, the team members involved with this project have moved onto other responsibilities. Whereas @johnnynek is very actively maintaining bazel-deps for use at Stripe.

[wstrange]

This repo should be deleted then - or marked with a big DEPRECATED warning.

If bazel-deps is the way to go, it should be moved under the bazelbuild/ project.

Maven migration is just insanely confusing for any newcomer to Bazel. Searching on google turns up several solutions that "mostly" work - but are not quite 100% (in our case, none seem to handle artifactory authentication...)

Bazel needs a single, well documented, well tested solution for maven migration.
