CLion doesn’t sync header files under includes dirs from implementation_deps

[sfc-gh-abalik]

Description of the bug:

• Given a cc_library (lib1) that includes another cc_library (lib2) via implementation_deps
• lib2 exposes lib2.h via includes

cc_library(
    name = "lib2",
    srcs = ["lib2.cc"],
    hdrs = ["include/lib2.h"],
    includes = ["include"],
)

cc_library(
    name = "lib1",
    srcs = ["lib1.cc"],
    hdrs = ["lib1.h"],
    implementation_deps = [
        ":lib2",
    ],
)

cc_binary(
    name = "helloworld",
    srcs = ["main.cc"],
    deps = [
        ":lib1",
    ],
)

CLion will not find lib2.h when syncing files in lib1

# File: lib1.cc

#include "main/lib1.h"
#include "lib2.h"     // => red squiggly here with "'lib2.h' file not found"   

std::string get_string() {
  print_something();  // => function from lib2.h not found  
  return "Hello world";
}

As a result intellisense, go to definition, etc don’t work for lib2.h.

A couple workarounds that fix this

• Changing from implementation_deps to deps
• Changing the #include to "include/lib2.h" (e.g. not relying on the include dir)

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Here's a full workspace with the example above. Just open the .bazelproject and look at lib1.cc.

Have you found anything relevant by searching the web?

#3352 seems similar, but for cc_binary

Any other information, logs, or outputs that you want to share?

I debugged this in the intellij_info_aspect and the problem seems to be that the include paths are not propagated from the implementation_deps to the target here. If I update the aspect to propagate includes from ctx.rule.attr.implementation_deps, then everything works as expected. I can put up a patch for this if it seems like the right fix.

NOTE - For deps this is not needed b/c all include paths are already propagated to downstream targets.

Exactly, so it could be caused because implementation_deps is missing here

@tpasternak I added a PR for this - #5220. Let me know if this approach makes sense.

Hi,

To up here, it's still relevant. If above code is working, can we consider please adding this to the plugin?
