oneof not working

[mingchuno]

I cannot compile a simple oneof message:

message Test {
  oneof haha_type {
    string a = 1;
    string b = 2;
  }
}

with the errors

[error] Expected "required", "optional", or "repeated".
[error] Missing field number.

I have tried to git clone your project and run e2e.sh, which lead to the same error:
