Visibility issue after upgrading from 6.3.0 to 6.5.0

[kmate-ct]

I'm unable to upgrade from 6.3.0 to 6.5.0... I get this error:

ERROR: .../external/io_bazel_rules_scala/scala/BUILD:39:22: in toolchain rule @io_bazel_rules_scala//scala:default_toolchain: target '@io_bazel_rules_scala_config//:scala_version_2_12_18' is not visible from target '@io_bazel_rules_scala//scala:default_toolchain'. Check the visibility declaration of the former target if you think the dependency is legitimate
ERROR: .../external/io_bazel_rules_scala/scala/BUILD:39:22: Analysis of target '@io_bazel_rules_scala//scala:default_toolchain' failed
ERROR: .../BUILD.bazel:6:14: While resolving toolchains for target //...: invalid registered toolchain '@io_bazel_rules_scala//scala:default_toolchain':

(I replaced some sensitive paths / target names with "...", but that should not matter)

Any ideas what am I doing wrong? I did not change my setup, only bumped the version.

[kmate-ct]

I see that the generated target is missing visibility

config_setting(
    name = "scala_version_2_12_18",
    flag_values = {":scala_version": "2.12.18"},
)

Is this intentional?

Also, if I force it to be visible, it doesn't get much better

external/io_bazel_rules_scala/scala/private/rule_impls.bzl", line 231, column 61, in allow_security_manager
        return ["-[Djava.security](http://djava.security/).manager=allow"] if java_runtime.version >= 17 else []

Error: 'JavaRuntimeInfo' value has no field or method 'version'

still using bazel 5.3.1, unfortunately... did the minimum bazel version change?

Should we just change rules_scala to use hasattr before calling .version or something?

[kmate-ct]

I'm not sure if this is the right fix but it "makes it work"

return ["-Djava.security.manager=allow"] if hasattr(java_runtime, "version") and java_runtime.version >= 17 else []

I guess if you are an a bazel that old you aren't also on a new jdk, so I think that fix should be fine if you send as a PR.

[kmate-ct]

Thanks, I will do so then. The original question was about the visibility of config_setting. Should I open a PR for that as well, or it might be something broken in my setup?

[kmate-ct]

I opened both PRs, we'll see I guess.

@kmate-ct thanks for the issue and PRs (both are merged)

[kmate-ct]

Thank you! Do you have any plan on the next release's date?
