java.lang.NullPointerException com.tikal.jenkins.plugins.multijob.MultiJobBuilder.getScmChange(MultiJobBuilder.java:168)
Issue Type: Bug Bug
Assignee: Unassigned
Components: multijob-plugin
Created: 19/Nov/15 3:36 AM
Priority: Minor Minor
Reporter: Luke Swithenbank

There was a null pointer exception on line 168 of com.tikal.jenkins.plugins.multijob.MultiJobBuilder. Look at the line at HEAD infers that lastbuild.getResult() is not being checked if null. http://javadoc.jenkins-ci.org/hudson/model/Run.html#getResult() implies that this will return null at some stage. Please put a null check before using lastbuild.getResult().
