The error message suggests either the tool you are using to invoke protoc does something wrong, or the configuration of that tool is wrong. You will need to share the content of your pom.xml file or some other build file you are using before someone can suggest a fix.

Thanks @xfxyjwf My project https://github.com/thinkerou/polyglot
reproduce it using the follow:

mvn clean install -U -Dcheckstyle.skip=true -T 4.0C
java -jar target/polyglot-1.0.0-SNAPSHOT.jar --command=list_services --proto_discovery_root=./src/main/proto --add_protoc_includes=.

Oh, I find to use the follow command it's OK a moment ago：

java -jar target/polyglot-1.0.0-SNAPSHOT.jar --command=list_services --proto_discovery_root=./src/main/proto

[xfxyjwf]

Hmm, it seems you are using a command line tool provided elsewhere. Can you create an issue against that project instead? The owner of that tool should have a better idea about how the tool should work. The error message above suggests the tool is invoking protoc with conflicting protos, but I have no idea where to look at.

OK, thanks again @xfxyjwf
