The error occurred in this line

shouldBuild = executor.shouldBuild( context.getScmResult().getChanges(),
project,

workingDirectoryService.getWorkingDirectory( project ),

context.getBuildDefinition() );

This may not be the cause of scm result being NULL at all. Could you check
if the project has a valid executorId?

In any case, I added a check if the executor is null and add some warning to
the logs.


Thanks
