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

             Summary: build.xml jar-all target does not include jython*.jar in lib/ directory 
                 Key: PIG-3667
                 URL: https://issues.apache.org/jira/browse/PIG-3667
             Project: Pig
          Issue Type: Bug
          Components: build
    Affects Versions: 0.11.1, 0.12.0
            Reporter: Suhas Satish
            Assignee: Suhas Satish


Pig package does not include the jython jar within lib/ directory  with the jar-all ant target but includes it in the "ant package" target. It should be including it in both targets as often, the build/ directory is excluded from packaging which is where ivy puts all the dependency jars while building under build/ivy/lib/Pig  

To reproduce:
ant jar-all 
rm -rf build/ 
bin/pig
grunt> register '/tmp/test.py' using jython as myfunction;

If done prior to installing jython, here's the error one gets:
2013-12-27 18:22:31,145 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
2998: Unhandled internal error. org/python/core/PyObject
Details at logfile: pig_*.log

Within the pig_*.log =>

Fix: Including jython*.jar within the lib/ directory gets rid of this issue and the UDF can be loaded- 
grunt>  register '/tmp/test.py' using jython as myfuncs;
