Please document how to generate Python sources

[massenz]

Reading #13, it states that setting this:

sourceSets {
  main {
    proto {
      builtins {
        python {
        }
      }
    }
  }
}

should generate python sources too; but I get an error:

A problem occurred evaluating root project 'ServerlessProtos'.
> Could not find method builtins() for arguments [build_7w3n39f0fdfgkgnm0to8jwh56$_run_closure6$_closure9$_closure10$_closure11@6ad993e4] on main Proto source of type com.google.protobuf.gradle.ProtobufSourceDirectorySet.

Be that as it may - this is, to say the least, non-intuitive.

How difficult would it be to have something like:

protobuf {
  ...
  generatePython = true
}

or something to that effect?

I am perfectly capable of creating a bash script to do both, but it would be nice to just run ./gradlew install and have both Java/Python generated.

Thanks!

The syntax from #13 is outdated. With the latest version of the plugin, you don't specify output in the sourceSets, but in the generateProtoTasks block. The minimal code would be:

protobuf {
  generateProtoTasks {
    // all() returns the collection of all protoc tasks
    all().each { task ->
      task.builtins {
        remove java
        python { }
      }
    }
  }
}

Thanks.
This issue was, in fact, about actually documenting this (I was just pointing out that searching around for suggestions, that was all I could find).

Unless you tell me it's a bad idea, I'd like to add that info to this project's README and submit a PR: would that be ok?

[zhangkun83]

It is already documented. Try searching for "python" in the current README. Feel free to make a PR if you find anything that can be improved.

ah, yes, completely missed it, sorry!
I've pushed a PR to make it a bit more prominent, hope this helps: I'm obviously grateful for the plugin, saves the effort of messing around with bash and stuff.
