[me@localhost myapp]$ java -jar effectivejava-0.1.2-SNAPSHOT-standalone.jar -l -d "/home/me/myapp"

Exception in thread "main" java.lang.ExceptionInInitializerError at java.lang.Class.forName0(Native Method)

at app.core.<clinit>(Unknown Source)

Caused by: java.lang.NullPointerException

Could not find the main class: app.core. Program will exit.
