Avro: How to define Protocol from AVDL?

Question

The reading od AVPR is easy:

Protocol protocol = Protocol.parse(new File("ht-proto.avpr"));

But this does not work for IDL files (AVDL).

How to read the AVDL file so I could accomplish the following task but using AVDL instead of AVPR:

public static void main (String[] args)  {
     Main.class.getResourceAsStream("net/protocol_man.avdl");
     Protocol protocol  =
           Protocol.parse(Main.class.getResourceAsStream("net/protocol_man.avpr"));
                                                   //this doesnt work for AVDL       
 }

Answer 1

If you are working with maven. you can add the following plugin.

this will create the java sources and with that you can do pretty much everything.

I mean you can later reference to one of the generated classes For example Event.class

and ask for it's Schema Event.$SCHEMA
