---------------------------------

             Summary: Set up mvn clean to delete the "build" directory as well
                 Key: OOZIE-3261
                 URL: https://issues.apache.org/jira/browse/OOZIE-3261
             Project: Oozie
          Issue Type: Improvement
          Components: build
            Reporter: Peter Cseh


There are folders named build in every project we have. They are taking up a ton of space and not cleaned away when executing "mvn clean" 
{noformat}
>> [84] 13:52 : oozie (master) :: du -sh */*/build
6.9M	sharelib/distcp/build
174M	sharelib/hive/build
1.8G	sharelib/pig/build
665M	sharelib/spark/build
498M	sharelib/sqoop/build
7.3M	sharelib/streaming/build
>> [85] 13:53 : oozie (master) :: du -sh */build
 23M	core/build
7.8M	minitest/build
6.2M	tools/build
{noformat}

They are containing a bunch of files generated during executions in the MiniCluster:

{noformat}


"mvn clean" should be configured to clean these folders up as well.
