Example to repro jdeps issue

[nkoroste]

Fails with jdeps:

cd examples/jdesp_issue
bazel build //libKtAndroid1:src_main_kt --@io_bazel_rules_kotlin//kotlin/internal/jvm:experimental_prune_transitive_deps=True --@io_bazel_rules_kotlin//kotlin/internal/jvm:kotlin_deps=True

Passes without jdeps:

cd examples/jdesp_issue
bazel build //libKtAndroid1:src_main_kt --@io_bazel_rules_kotlin//kotlin/internal/jvm:experimental_prune_transitive_deps=True --@io_bazel_rules_kotlin//kotlin/internal/jvm:kotlin_deps=False

error: supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class examples.deps.libktandroid2.KtDummy2, unresolved supertypes: examples.deps.libktandroid3.KtDummy3
Adding -Xextended-compiler-checks argument might provide additional information.

Probably caused by https://github.com/bazelbuild/rules_kotlin/pull/807

In theory, I think if the build doesn't fail without jdeps then it should also not fail with jdeps - @aeremin thoughts?

I no longer think that this PR is an issue. As it fails just the same when I revert it.

[oliviernotteghem]

Correct. Issue is not caused by https://github.com/bazelbuild/rules_kotlin/pull/807, it's caused by JdepsGenExtension invoking supertypes() kotlintype API (here). This call will cause (lazy) resolution of the type, and will cause an error since corresponding class is missing on classpath.

Why is compilation succeed then? See Pavel's comment on this issue

having a type with missing supertypes doesn't always mean that the old error will be reported

So, your best bet is to fix your project and add the missing dep :(
