Exclude some .proto files while using compileMavenTypes

[flipp5b]

I have a Maven artifact containing .proto files only (without pre-compiled classes). I want to generate classes from this protos in my project (project itself doesn't have own .proto files). So, I use <compileMavenTypes>direct</compileMavenTypes> and <includeStdTypes>true</includeStdTypes> (protos from the artifact includes some standard Google's protos). Everything is great but plugin generates classes for all dependencies including protobuf-java (which already contains pre-compiled classes) and this leads to class duplication.

Probably, this is not a big issue (since classes are the same), but I wonder if there is any way to exclude some protos from code generation?

It is a problem, because they're not the same. The StringValue.class in protobuf-java.jar contains the StringValue.of(String) method that is not present if one simply passes StringValue.proto to protoc!
