How redeploy application on Google App Engine?

Question

I couldn't find it in the documentation, so help me please.

When I want to deploy WAR file to Google App Engine, I just clone it from git in the cloud shell and press

mvn appengine:deploy

And application successfully deploys and starts. So I have a question, when I'm fixing something, pushing in git, how to make application stop and redeploy with new, pulled changes?

Answer 1

使用诸如Jenkins或Hudson之类的持续集成工具，或编写您自己的服务，该服务将在检测到代码库中的更改后进行重新部署。
