Small project to test
- Google Cloud Endpoints
- with Google AppEngine Standard Environment (Java8)
Build with gradle, especially
The project currently works as expected when deployed Try here, but doesn't work locally.
You need to adopt the following to deploy it on you own.
- in /common.gradle, replace cliendId and appId with your settings from the cloud console.
- in src/main/webapp/index.html, replace the hostname of your app.
- in src/main/de.klpv.api.config.Constants, replace the clientId.
First you need to comment the <runtime>java8</runtime> like <!--runtime>java8</runtime--> to use the java7 dev server.
If you don't comment the java8 runtime, you'll get the following exception:

When the entry is commented, you can just start the local dev server:
gradle appengineRun
Then try http://localhost:8080 and you should see an alert with "Hi Marco".
gradle appengineDeploy
Then try the URL of your app and you should see "Hi Marco".
