These are the instructions to run the Integration tests for the Gcloud plugin. The tests will build the plugin, then build a simple Java Application, deploy it to a App Engine project (maven-plugin-test-app.appsport.com), set it as the default version and run a script () that pings the servlet.
mvn clean install invoker:integration-test
The build log will be in the target directory: /target/it/gcloud-maven-plugin-test-app/build.log
