cannot load '@rules_jvm_external~5.2~maven~maven//:compat.bzl': no such file
Closed this issue · 3 comments
enola-dev/enola#161 is a PR which upgrades Bazel from 6.1.2 to 6.2.0.
That upgrades causes the following build failure, which did not occur before the upgrade:
ERROR: Error computing the main repository mapping: cannot load '@rules_jvm_external~5.2~maven~maven//:compat.bzl': no such file
I looked into this a bit, and gather that this may or may not have something to do with #880 from @shs96c which was reviewed by @cheister which is mentioned on https://github.com/bazelbuild/rules_jvm_external/releases/tag/5.2?
I indeed cannot find a compat.bzl in this repo, but there are example referencing it, incl. https://github.com/bazelbuild/rules_jvm_external#repository-aliases (and there is a compat_repository.bzl (which doesn't seem to have moved in a while).
My WORKSPACE.bazel looks like the example on the README.
What am I missing?
In the https://github.com/bazelbuild/rules_jvm_external/tree/master/examples/simple, the https://github.com/bazelbuild/rules_jvm_external#repository-aliases works as documented. So this problem is specific to my project (above).
I suspect that @maven//:compat.bzl isn't the same. When I "intentionally break" the working example, it fails as:
ERROR: Error computing the main repository mapping: cannot load '@@maven//:compat--BAD.bzl': no such file
where as in my project it fails as:
ERROR: Error computing the main repository mapping: cannot load '@@rules_jvm_external~5.3~maven~maven//:compat.bzl': no such file
I don't quite understand what defines the @maven repository.
In my project there is a bit of a mix of a maven_install(artifacts = IO_GRPC_GRPC_JAVA_ARTIFACTS, ... in my WORKSPACE.bazel as well as a maven.install(... in my MODULE.bazel.

That was it! enola-dev/enola#387 temporarily worked around this (ugly, but it works; I will look into a cleaner solution later), and enabled enola-dev/enola#388 and enola-dev/enola#389 and enola-dev/enola#161 and enola-dev/enola#390 (#NOK).
