I am trying to setup
Maven with RAD7.
I have created Maven project for simple web application. (struts2+jsp).
I have added dependency for struts2-core in pom.xml.
But when I run pom.xml I am getting following exception. I don't see rootcause for this exception which is making more harder for me to trouble shoot.
Have any of you encountered same exception?
Versions that I am using:
Maven:apache-maven-2.0.9
Struts2
Exception in
thread "main" java.lang.NullPointerException
