Hello, You need to install scala and make sure that its bin directory on you PATH: I am assuming that SCALA_HOME is the place you will install scala. I am using scala-2.11.8. export PATH=$SCALA_HOME/bin:$JAVA_HOME/bin:$ANT_HOME/bin:$HADOOP_HOME/bin:$PATH Hope this helps, best regards, Mahmoud Parsian

Also, you can build with maven:

mvn clean package
