Hi Pratyaksh, run_travis_tests,sh not run `mvn clean`, You can try to run `mvn clean` manually before integration test.
BTW, if you use IDEA, you can do `mvn clean package -DskipTests -DskipITs -Pspark-shade-unbundle-avro` first, then just run integration test in IDEA like unit test does. But, there are something to notice here: you need a runnable spark and SPARK_HOME should in env. Regards hddong
