Subject [jira] Resolved: (MAHOUT-96) grouplens-example erroneous path to .dat files

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.

> 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.
