       --plugin=protoc-gen-grpc-java \
       --grpc-java_out=output_java  \
        -Iproto/ \
        $(find proto/* -iname "*.proto")

simple convert for Swift

protoc --swift_out=output_swift  \
       --swift_opt=FileNaming=PathToUnderscores \
       --plugin=protoc-gen-grpc-swift \
       --grpc-swift_out=output_swift  \
       --grpc-swift_opt=FileNaming=PathToUnderscores \
        -Iproto/ \
        $(find proto/* -iname "*.proto")

Notice

cosmos modified proto's default library file. for just simple drag&drop for your project, you should modify your proto files import

import "google/protobuf/any.proto";
-->
import "google/protobuf2/any.proto";
