[IDE integration] code not resolving under "transitive" mode

[wisechengyi]

I have created a minimal repro at https://github.com/bazelbuild/rules_scala/pull/1358/files

3 targets: a -> b -> c. Temporarily setting the following for scala toolchain to show the point.

--- a/scala/BUILD
+++ b/scala/BUILD
@@ -23,7 +23,8 @@ toolchain(
 
 scala_toolchain(
     name = "unused_dependency_checker_error_toolchain_impl",
-    unused_dependency_checker_mode = "error",
+    unused_dependency_checker_mode = "off",
+    dependency_mode = "transitive",
     visibility = ["//visibility:public"],
 )

When importingtmp/src/scala/a into intellij with the bazel plugin:

directories:
  tmp/src/scala/a

# Automatically includes all relevant targets under the 'directories' above
derive_targets_from_directories: true

targets:
  # If source code isn't resolving, add additional targets that compile it here

additional_languages:
  scala

You can see that B can resolve correct, but C fails to resolve.

So was wondering if it's a rules_scala issue that it fails to let bazel plugin's aspect know about C, or a bazel plugin issue for asking for too little?

References

• Importing tmp/src/scala would have C resolved.
• building aworks just fine:
