    Question from a new guy. Null pointer from getting started

    Tyler Christensen Newbie

      Hey,

      This is my first every post in a community site, so please go easy on me if I miss some really basic things.

       

      I am trying to become familiar with Arquillian, but I am having some trouble.

      I have gone through "Getting Started" step by step a couple times to try and get my first "green bar" (successful test)

      Although I have followed the steps exactly, I get:

      java.lang.NullPointerException

      I cannot seem to figure out exactly why.  Any help would be very much appreciated

      I am running

      ubuntu 14.04,

      java 7,

      Eclipse EE IDE (Luna) w/ jboss tools

       

      Thank you

       

       

      POST Answer:

       

      Even though the test runs successfully and gives a green bar, this line:

      23 [main] INFO org.jboss.weld.Version - WELD-000900 1.1.5 (Final)

      Still comes up in red colour. Does that indicate an error that will give me problems in the future?

          I got the green bar!!

          Troubling thing, is I didn't ever pinpoint the location.

          I figured it was a problem with dependencies and/or versions thereof.

          I was also using custom maven settings with artifactory running on a local server. I disabled those settings and deleted the downloaded dependencies from my .m2 directory. I then redownloaded them and ran Maven update with the option to force update of snapshots/releases

           

          After that, when I ran the test it was a success.
