Support for Proto3 well known types

First of all, thanks for this plugin, very useful.

Is your feature request related to a problem? Please describe. I am using proto3, and importing some well know types. It seems that these are not currently supported out of box, since I am getting a “File not found” error on the import, and an “Unresolved reference” error on all usages.

Describe the solution you’d like It would be great if protobuf/src/google/protobuf/ was automatically added as an include path of this plugin.

Additional context

Example:

syntax = "proto3";

import "google/protobuf/timestamp.proto";

package myproto;

message MyMessage {
    google.protobuf.Timestamp created_at = 1;
}

A few other experiments.

Opening /hello_go with IntelliJ

This does not seem to be a Goland specific issue per se, since repeating the same 3 steps with IntelliJ instead of Goland leads to the same result.

Opening /hello_java with IntelliJ

Interestingly, repeating the same 3 steps with IntelliJ and with the hello_java folder does not lead to any issue:

However, inspecting the project structure or navigating to the declaration of google.protobuf.timestamp show that the plugin picks it up not from the bundled protobuf distribution, but from the "com.google.protobuf:protobuf-java:3.7.0" gradle dependency required for the generated java code to compile.

Opening / with Golang

Finally, opening the root folder of the repo with Goland works fine:

And in that case, the bundled protobuf distribution appears in /.idea/MRE_protobuf_plugin.iml:

<?xml version="1.0" encoding="UTF-8"?>
<module type="WEB_MODULE" version="4">
  <component name="Go" enabled="true" />
  <component name="NewModuleRootManager">
    <content url="file://$MODULE_DIR$" />
    <orderEntry type="inheritedJdk" />
    <orderEntry type="sourceFolder" forTests="false" />
    <orderEntry type="library" name="Bundled Protobuf Distribution" level="application" />
  </component>
</module>

Conclusion

So to me, the issue seems to stem from the fact that both IntelliJ and Goland only include the bundled protobuf distribution if there is a .proto file within the project.

I hope that helps, thanks for the time you are spending on this.
