Thejas M Nair commented on PIG-1390:
------------------------------------
I had to make some changes after applying the patch to get things working for
me.
I removed "test/org/apache/pig/test" from the sources, because "test" is
already present . Before I removed it was getting eclipse error saying
something like 'could not add this dir because "pig/test" is already there'.

Some of the jars from "lib/" dir were missing . These libs also need to be
exported so that pig (org.apache.pig.Main) can be run from eclipse.
The classes were not being generated by eclipse into build/eclipse-classes . I
had to change "output" to build/classes to fix the class-not-found exception I
was getting when I tried running org/apache/pig/Main.java from eclipse .

I also noticed that if the project is added to eclipse after 'ant
eclipse-files' is run, it has problems with seeing the files under src-gen .
But that is probably just something that needs to be documented.
I tried all this on Eclipse Version: 3.4.2 on a mac .
Can you please try out these changes and see if it works for you ?
