Hello,
So actually solved the problem...see point 3. Here are a few approaches/errors I was getting: 1) mvn package exec:java -Dexec.mainClass=HelloWorld Error: java.lang.ClassNotFoundException: HelloWorld 2) http://stackoverflow.com/questions/26929100/running-a-scala-application-in-maven-project same error as above 3) The solution I found was here: http://www.scala-lang.org/old/node/345 It seems to be similar to 2, but the build seems to include a few more things. So it does seem that a few things have to be added to the pom for it to work for scala, this was something I was a bit confused about after reading the book. Thanks for the help! Best, Su
