Subject Re: way to run unit tests from inside IDE?
Date Sat, 29 Oct 2011 06:36:56 GMT
I use Eclipse and it's okay for running unittests, but I need to set the 
VM args in the junit run configuration for each specific test to 
-Dprop.jarLocation=target/giraph-0.70-jar-with-dependencies.jar.  I 
assume you need to do the same for Intellij.

This is done in pom.xml when doing 'mvn test' and other mvn commands.
