Subject Re: How should I migrate 1.4 code to avro 1.5?

Some comments:

You should check in the *.avdl or *.avsc file that describes your MyPair
schema instead of the generated code.  Maven can be used to generate the
Java class using the avro-maven-plugin.

For example, add:

To your pom to compile *.avsc files from src/main/avro  into

For more help on this, add the plugin above to your pom, and type:

'mvn avro:help'  for basic documentation, or 'mvn avro:help ­Ddetail=true'
for full documentation on the maven plugin.

Some IDE's are a little picky with this (especially Eclipse, and moreso with
recent versions) and you may need to manually generate the source from
command line or in the IDE  ('mvn generate-sources');
