SparkJava Example Deployment to App Engine fails

[eneskaya]

When trying to deploy the sparkjava Example to App Engine using mvn appengine:deploy I get two errors, regarding the placement of the Dockerfile and the .jar file.

First, I get this:

[ERROR] Failed to execute goal com.google.cloud.tools:appengine-maven-plugin:1.0.0:deploy (default-cli) on project getwhocares: Execution default-cli of goal com.google.cloud.tools:appengine-maven-plugin:1.0.0:deploy failed: Found 'Dockerfile' in the App Engine directory. Please move it to the Docker directory. -> [Help 1]

To fix that issue I copied the Dockerfile from the /src/main/appengine directory to /src/main/Docker. After that, it's not complaining anymore, but the second error occurs:

When running it locally it all works fine.
What's wrong here?

@jerjou Looks like we need a deployment test for the SparkJava sample. Could you look into this / fix the sample & add tests to Jenkins?

Added deployment test.
