Brian Femiano commented on GIRAPH-159:
--------------------------------------
I figured out what's causing it.
It's a result of adding my hbase dependency to the pom.xml
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase</artifactId>
<version>0.92.1</version>
</dependency>
Compile the jar and you should see a new 'license' directory.
jar tvf giraph-0.2-SNAPSHOT-jar-with-dependencies.jar | grep -i 'license'

> 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
> Attachments: GIRAPH-159.patch, compile.xml
>
>
> 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.
