Description
Trying to build avro-java from svn trunk fails in checkstyle:
"Unused import - org.apache.avro.UnresolvedUnionException" in
ipc\src\main\java\org\apache\avro\specific\SpecificResponder.java
I had to run with -Dcheckstyle.skip=true to get anywhere. Maybe consider running checkstyle only on demand or on the build server (set "skip" property from default false to true in the pom and pass skip=false to enable when required).
