appengine-skeleton

This is a generated application from the appengine-skeleton archetype.

See the Google App Engine standard environment documentation for more detailed instructions.

Java 8
Maven (at least 3.5)
Google Cloud SDK (aka gcloud)

Setup

gcloud init
gcloud auth application-default login

Maven

Running locally

mvn appengine:devserver

Deploying

mvn appengine:update

Testing

mvn verify

As you add / modify the source code (src/main/java/...) it's very useful to add unit testing to (src/main/test/...). The following resources are quite useful:

Junit4
Mockito
Truth

Updating to latest Artifacts

An easy way to keep your projects up to date is to use the maven [Versions plugin][versions-plugin].

mvn versions:display-plugin-updates
mvn versions:display-dependency-updates
mvn versions:use-latest-versions

Note - Be careful when changing javax.servlet as App Engine Standard uses 3.1 for Java 8, and 2.5 for Java 7.

Our usual process is to test, update the versions, then test again before committing back.
