Compiling scalastyle fails

[Leo GL]

I would like to compile the scalastyle so I download the scalastyle zip from githut and import it into eclipse as a maven project. Calling mvn scala:compile produces following output:

Could anyone explain me how to solve the problem? Thanks.

I don't understand why it doesn't work for you.

You shouldn't need to do scala:compile - mvn compile should just work.

Are you sure that the version that you've cloned is correct? What is the result of the following command?

$ git rev-parse HEAD

Thanks.
