I have a standalone java project. I have performed a maven clean install. I now go into the target\\classes folder via command prompt and set all the required files in class
It seems -cp and -jar are incompatible. You need to put the classpath in the manifest
See http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html
If you want maven to automatically update the classpath, see: -
