Flag --incompatible_no_implicit_file_export will break Cloud Robotics Core in a future Bazel release

[bazel-flag-bot]

Incompatible flag --incompatible_no_implicit_file_export will be enabled by default in a future Bazel release [1], thus breaking Cloud Robotics Core.

The flag is documented here: bazelbuild/bazel#10225

Please check the following CI builds for build and test results:

• Ubuntu 18.04, OpenJDK 11

Never heard of incompatible flags before? We have documentation that explains everything.

If you don't want to receive any future issues for Cloud Robotics Core or if you have any questions,
please file an issue in https://github.com/bazelbuild/continuous-integration

Important: Please do NOT modify the issue title since that might break our tools.

[1] The target release hasn't been determined yet. Our tool will update the issue title once the flag flip has been scheduled.
