Sean Owen resolved MAHOUT-96.
-----------------------------
Resolution: Fixed
It's not possible to share an Ant env variable into the Java code. At some
level it kinda has to be hard-coded, the path where the resource lives in the
jar file.
However there was a problem with how these files were packaged -- they weren't
getting put into the .jar! I addressed this.

> Key: MAHOUT-96
> URL: https://issues.apache.org/jira/browse/MAHOUT-96
> Project: Mahout
> Issue Type: Bug
> Components: Collaborative Filtering
> Reporter: Jens Grivolla
>
> GroupLensDataModel.java tries to read from
> "src/example/org/apache/mahout/cf/taste/example/grouplens/ratings.dat"
> whereas the file is included in taste-build.xml from
> "${grouplens-location}/ratings.dat".
> The location is hard-coded in GroupLensDataModel.java and would need to be
> changed to conform to the current code organization. A better solution would
> be not to hard-code the path.
