Failed to deploy Google APP Engine Java /Maven

Question

I'm trying to deploy my java/Maven application on Google Cloud App Engine, but without success I'm getting the following error:

[ERROR] Failed to execute goal com.google.cloud.tools:appengine-maven-plugin:2.4.2:deploy (default-cli) on project reembolso: Execution default-cli of goal com.google.cloud.tools:appengine-maven-plugin:2.4.2:deploy failed: com.googl e.cloud.tools.appengine.operations.cloudsdk.AppEngineJavaComponentsNotInstalledException: Validation Error: Java App Engine components not installed. Fix by running 'gcloud components install app-engine-java' on command-line. -> [He lp 1]

The pom file is configured like this:

If you are on Windows, running gcloud components install as an administrator may work: GoogleCloudPlatform/app-maven-plugin#393 (comment)
