Use maven lock-file

[scaiper]

This PR enables use of a lock-file for kotlin_rules_maven repo. This in turn enables caching and reproducible builds.
Had to bump rules_jvm_external to 6.0 and some of its transitive deps.

Not sure where this error comes from in the failed check. Seems unrelated.

You might need to downgrade rules_jvm_external and file an issue upstream for this one.

I'm not sure what to report. I guess use_repo_rule was not available in bazel 6.4.0, which is used in this one test.

[scaiper]

Indeed, use_repo_rule is a 7.x feature. So questing is, is support of 6.x bazel important or it could be dropped?
If 6.x support is desirable, I quess I should try to make it work without bumping the versions.

[Bencodes]

@scaiper can your rebase this branch? I bumped the rules Bazel version to 7.1.0 to see if that helps with compat.

[scaiper]

Version 7.0.2 is fine. Problem is with this test https://buildkite.com/bazel/rules-kotlin-kotlin/builds/4060#018e4350-c427-4f5d-a54f-4a7ef3c694b1

So questing is, is support of 6.x bazel important or it could be dropped?

At the moment we try to keep compatibility with 5.x, 6.x, and 7.x https://github.com/bazelbuild/rules_kotlin?tab=readme-ov-file#rules_kotlin-bazel-compatibility

Something that's odd is this example test shouldn't even be using Bzlmod https://github.com/bazelbuild/rules_kotlin/blob/be6fb59f169ac6e1dcbf395c325462343a68214b/.bazelci/presubmit.yml#L59C3-L67

[scaiper]

Shouldn't the flag --enable_bzlmod=false also be specified in the build_flags?

[scaiper]

It's bazel info command that failed, apparently it also needs the --enable_bzlmod=false flag.

I've managed to make it work using current versions of dependencies, so I've reverted version bump.
