Jeff Hodges commented on AVRO-503: ---------------------------------- Oh, and to get this up and running I did this: {quote} cd $AVRO_PROJECT wget https://issues.apache.org/jira/secure/attachment/12440724/cass.tar.gz --no-check-certificate tar xzvf cass.tar.gz cd cass mkdir -p build/classes . clspth find . -name "*.java" | xargs javac -d build/classes ./start {quote} I'm sure there's a quicker way but that worked.
