protobuf Android导入文件

Question

更多文件导入版本会出错，android build.gradle：

Cause: protoc: stdout: . stderr: C:\Users\admin\Desktop\WxDemo\app\build\extracted-include-protos\main: warning: directory does not exist.
C:\Users\admin\Desktop\WxDemo\app\src\debug\proto: warning: directory does not exist.
./app/src/main/java/proto/protobuf.proto: Backslashes, consecutive slashes, ".", or ".." are not allowed in the virtual path
./app/src/main/java/proto/protobuf_request_response.proto: Backslashes, consecutive slashes, ".", or ".." are not allowed in the virtual path
protobuf_main.proto: Import "./app/src/main/java/proto/protobuf.proto" was not found or had errors.
protobuf_main.proto: Import "./app/src/main/java/proto/protobuf_request_response.proto" was not found or had errors.
protobuf_main.proto:10:14: "CMD_SERVICE" seems to be defined in "protobuf.proto", which is not imported by "protobuf_main.proto".  To use it here, please add the necessary import.

Build.gradle：
