Issue with running Spark from sources

Hello,

I am trying to run Spark with maven as in the readme (mvn exec:java) but I’m having some issues with MojoExecutionException thrown in class Startup. I need the maven project for a university project and I would really appreciate some more hints on how to properly build it. Thanks for the help!

Do you have to build it from command line? I use IntelliJ to edit code, so i build it in there.
