import does not work correctly

[Mask051]

org/a/a.proto

syntax = "proto2";
package org.a;

message Msg {
extensions 16 to max;
}

org/b/b.proto

syntax = "proto2";
package org.b;
import "org/a/a.proto";

extend Msg {
optional Test test = 16;
}

message Test {}

These configuration throws error while compiling:

On a fast first read, it seems like the error is generated by protoc, not ScalaPB. In b.proto, the package name is missing. Can you try:

extend org.a.Msg {
  optional Test test = 16;
}

This should pass protoc, though ScalaPB currently does not support extensions.

It works. Thanks
