What is really interesting... why do all test run successfully (without
-DskipTests)? Looks like the tests seem different to the true environment.
Here to build with main branch:

> Mahout Source Broken
> --------------------
>
> Key: MAHOUT-2093
> URL: https://issues.apache.org/jira/browse/MAHOUT-2093
> Project: Mahout
> Issue Type: Bug
> Components: Algorithms, Collaborative Filtering, Documentation
> Affects Versions: 0.14.0, 0.13.2
> Reporter: Stefan Goldener
> Priority: Blocker
>
> Seems like newer versions of Mahout do have problems with spark bindings e.g.
> mahout spark-itemsimilarity or mahout spark-rowsimilarity do not work due to
> class not found exceptions.
> {code:java}
> Error: Could not find or load main class
> org.apache.mahout.drivers.RowSimilarityDriver
> {code}
> {code:java}
> Error: Could not find or load main class
> org.apache.mahout.drivers.ItemSimilarityDriver
