Contains many editorial improvements to and some extra information in the README, along with a few small improvements to the code. Broken out from bazelbuild#1710, and part of bazelbuild#1482 and bazelbuild#1652. Specifically: - Adds more info on translating `@rules_scala` to `@io_bazel_rules_scala` for dependencies via repo mapping. - Merges information about the previously planned `rules_scala` 8.0.0 release into the information for 7.0.0, since it seems we may make only one major release. - Improves information about `protobuf` support for versions before v28, Scala 2.11, and the upcoming Bzlmod `compatibility_level` setting. - In `scala_config.bzl`, changes the private `_default_scala_version()` to the public `DEFAULT_SCALA_VERSION`. - Adds `allow_empty = True` to a `glob` expression in `//test/semanticdb:lib_with_tempsrc`. - Removes Scala 2.11 test cases from `test_thirdparty_version.sh` and `test_version.sh`. This change is smaller and more focused than bazelbuild#1710, and should ultimately make that pull request smaller and/or easier to review. The motivations for the individual changes are: - The public `DEFAULT_SCALA_VERSION` constant makes this value accessible to the upcoming module extension. - `glob` requires an explicit `allow_empty = True` parameter in Bazel 8, in which `--incompatible_disallow_empty_glob` defaults to `True`. - ScalaPB 0.9.8, the last version compatible with Scala 2.11, does not support `protobuf` v25.6 or later. For this reason, we must remove the Scala 2.11 test cases, as documented in the `README.md` updates. See also bazelbuild#1712. We should consider dropping Scala 2.11 support at this point, since there's no ScalaPB release for it that supports later versions of `protobuf`. That, and we could remove some of the special case code added in the following changes, amongst other 2.11 support details: - bazelbuild#1631 - bazelbuild#1648 - bazelbuild#1687 - bazelbuild#1688
Provided a better explanation for using `rules_python` 0.38.0 for now. Improved some of the language in the Bazel 6.5.0 compatibility section.
