   I had a different Maven error- seems like it ran out of memory, perhaps due to configuring additional druid extensions
   
   ```

   I was able to resolve by adding the following line to the included [Dockerfile](https://github.com/apache/druid/blob/master/distribution/docker/Dockerfile#L21)
   
   `RUN export MAVEN_OPTS="-Xmx1g -XX:+UseCGroupMemoryLimitForHeap"`
   
   I suspect only one of the two options I added did the trick, but that might depend on your version of java.
   
   Sorry for the slightly tangential comment, but might be useful to look at other possible `MAVEN_OPTS`- and might help in case anyone else has the same issue I encountered
