This will ensure that the build keeps going even if there is an error,
so that we can see as many results as possible without having to fix the
error and kick off another run.
* [bazel] Move Java runtime/toolchains into //java
This change moves `java_library` targets from the top-level BUILD file
into `//java/{core,lite,util}` and declares `alias` targets to point to
their new locations (hence, this is not a breaking change).
This will allow users that don't use Java to stop depending on
`@rules_java` (e.g. as requested in
https://github.com/bazelbuild/rules_scala/pull/989#issuecomment-583405161).
Note that there is no intention to deprecate + remove the top-level
targets in the foreseeable future.
* Add BUILD files in //java to java_EXTRA_DIST
I'm not exactly sure why, but this fixes the failing Bazel presubmit
test. Using the most recent version seems like a good idea anyway so
that we can make sure we're compatible with any new Bazel changes.
