Case insensitive file/directory name matching will produce errors on M/R jar 
unpack.

                 Key: GIRAPH-159
                 URL: https://issues.apache.org/jira/browse/GIRAPH-159
             Project: Giraph
          Issue Type: Bug
          Components: build
    Affects Versions: 0.2.0
         Environment: OSX 10.6.8
            Reporter: Brian Femiano


This only seems to affect platforms where there can be a file/directory naming 
conflicts
from case insensitive matches. 
 
I was able to reproduce running the pseudo-distributed unit tests within OSX.

This has affected other projects: 
https://issues.apache.org/jira/browse/MAHOUT-780

I've been able to reproduce this on my local OSX install with the following 
error:
https://groups.google.com/a/cloudera.org/group/cdh-user/browse_thread/thread/a201218000e956d3/cc6eca3ef9f80ff8

Since LICENSE.txt contains the same content as the file LICENSE, I propose we 
exclude any LICENSE matches found in the unpacked dependency jars
when the maven assembly phase hits 'jar-with-dependencies'. 

I have a patch which moves the 'jar-with-dependencies' descriptor to an 
external compile.xml file which has the proper excludes. This might also
come in handy down the road should any additional tweaks be needed to the 
compile phase.
