Need to find the way to update the build descriptor with the cause of the build failure

[p***@gmail.com]

Hi All,

Trying to update the build descriptor with the build cause found through
the "build analyser plugin".

Here is the groovy Post Build Script using to update the build descriptor:
=========
import hudson.model.Action
import hudson.model.BuildBadgeAction
import hudson.model.ModelObject
import com.sonyericsson.jenkins.plugins.bfa.model.FailureCauseBuildAction
def action =
manager.build.getAction(com.sonyericsson.jenkins.plugins.bfa.model.FailureCauseBuildAction.class)
def causes = action.getFoundFailureCauses();
manager.build.setDescription(causes[0].getDescription())
============


But this is failling with Error :

java.lang.NullPointerException: Cannot invoke method getFoundFailureCauses() on null object
at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:91)
at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:48)
at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
at org.codehaus.groovy.runtime.callsite.NullCallSite.call(NullCallSite.java:35)
at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
