Error when using AutoBazelRepository annotation processor

[SanjayVas]

My assumption is that kt_jvm_library does not pass -Abazel.repository the way that java_library does. See bazelbuild/bazel#16549

error: The bazel.repository annotation processor option is not set. To use this annotation processor, provide the canonical repository name of the current target as the value of the -Abazel.repository flag.

+1, had to use dirty workaround

genrule(
    name = "generate_env",
    outs = ["resources_root.env"],
    cmd = "echo $(rlocationpath //path/to/test/resources:test_files_root) > \"$@\"",
    tools = ["//path/to/test/resources:test_files_root"],
)

kt_jvm_test(
    name = "kt-idea-plugins-shared-library-test",
    srcs = ["kotlin/JsonAssemblerTest.kt"],
    resources = [
        # resources_root.env
        ":generate_env"
    ],
    test_class = "some.package.shared.JsonAssemblerTest",
    data = [
        ":generate_env",
        "//path/to/test/resources:test_files" # this is filegroup
    ],
    deps = [
        "//:kotlin_serialization",
        # some more deps
    ],
    env = {
        "REPOSITORY_ROOT_ENVFILE": "path/to/test/resources_root.env"
    }


)

and then in kotlin:

    fun getRepositoryRootPath(): Path {
        // there is file resources_root.env in this jar
        val classLoader = this.javaClass.classLoader
// env file name is in env variable REPOSITORY_ROOT_ENVFILE
        val resourcesRootEnv = classLoader.getResource(
            System.getenv("REPOSITORY_ROOT_ENVFILE")
        ) ?: throw Exception("resources_root.env not found")
        // read it, there is one string that consists repository root path
        val repositoryRootPath = resourcesRootEnv.readText()

        val runfiles = Runfiles.preload()
        val repositoryRootRLocation = runfiles.unmapped().rlocation(repositoryRootPath)

        // the path we have is to file `.test_resources_root` in test resources directory,
        // so we need to get parent of it
        return Path(repositoryRootRLocation).parent
    }

Maybe there is better workaround, but at least this one works
