I am struggling with Google App Engine. All I want to do is this:
I am following the exact steps of the tutorials. I have tried several times now. The app builds fine in Jenkins (I manage to get it running) however the deployment fails.
+ gcloud --project=MyProject preview app deploy target/guestbook-1.0-SNAPSHOT.war
ERROR: File [/var/jenkins/workspace/MyProject/target/guestbook-1.0-SNAPSHOT.war] is not a valid deployable item.
ERROR: (gcloud.preview.app.deploy) Errors occurred while parsing the App Engine app configuration:
Build step 'Execute shell' marked build as failure
Finished: FAILURE
It all works fine on the local development web server. The MyProject is the project id (I just changed it for the example). What am I doing wrong. I mean have I forgotten to do something? I have been doing Java for over five years now, I can't understand why it should be so hard to do something so basic. Please help me

What am I doing wrong, am I missing something? I have followed the guides exactly as they say.
I have tried to using Google Source as repository and Github. Nothing works.
EDIT:
It works:

It's failing to deploy because your jenkins build script is failing:
Build step 'Execute shell' marked build as failure
During the step "Execute shell", you have to make sure that the script returns with status 0. Anything else is considered failure. See this SO answer to a similar issue.
It appears that your "Execute shell" section is this one:
[MyGuestbook] $ /bin/sh -xe /tmp/hudson5523568617447680772.sh
+ gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT.war
ERROR: File [/var/jenkins/workspace/MyGuestbook/target/myapp-1.0-SNAPSHOT.war] is not a valid deployable item.
ERROR: (gcloud.preview.app.deploy) Errors occurred while parsing the App Engine app configuration:
Build step 'Execute shell' marked build as failure
Finished: FAILURE
This "Execute shell" sections of the build is failing because the status code returned from the script seems to be the status code returned from gcloud command. If you check the docs here, you can see that it doesn't accept .war archives, but only unpacked war folders. You can simply change the line from
gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT.war
to
gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT
and at this point, the "Execute shell" section of the build will run properly, and so the jenkins build as a whole should complete correctly.
Gradle
If you're using gradle for the build, it is likely already producing an exploded app directory:
build/exploded-app
