      Hi Team,

      I have configured GClound SDK plugin and included gcloud cli in the job,

      While executing a job it fails due to null pointer exception

      Here is the log

          [JENKINS-63640] Null pointer exception on GCloud SDK 0.0.3 version

          We are seeing very similar errors of the above described pattern occurring very rarely (one out of hundreds of build). It's always a "bug in the code" with an NPE following the "Modules changed, recalculating dependency graph"

          1. Modules changed, recalculating dependency graph
2. ERROR: Processing failed due to a bug in the code. Please report this to the issue tracker (https://jenkins.io/redirect/report-an-issue).
3. debug output with Maven project info (project, modules, rootModule)
4. java.lang.NullPointerException

          And the debug output comes straight from this line of the maven-plugin:
          https://github.com/jenkinsci/maven-plugin/blob/master/src/main/java/hudson/maven/MavenModuleSetBuild.java#L935

          In my case, the project, project.getModules(), and project.getRootModule() are never empty, but always match the actual Maven coordinates of the build that was running.

          I've been doing some investigating, this error is caused because the gcloud SDK is not installed on the Jenkins machine.  I added the gcloud sdk to my docker image and the command now runs . 

          I think the issue can be closed, but a trap at GCloudBuildWrapper.java line 92 for a missing gcloud with a sensible error message would be helpful.
