I found a way around this. If I put all three schemas in a single JSON
array, in a single JSON document in a file, and parse that file using the
ant SchemaTask, then it works -- it generates classes for all three
schemas. I assume it will also work when parsing the schema using other
I don't see this documented anywhere and I found it by trial and error. My
guess is that the top level array is treated as an Avro union, and the
SpecificCompiler doesn't happen to output this top level union type.
I don't know if it is meant to work this way (i.e, will continue to work in
the future), or is just a coincidence. Does anyone know?
