Java 8 console application.

[Pavlo M]

Hello.

I have a Java application and it packed to jar with Oracle JDK 8, so I can run it in command line shell. It makes http requests and stores some data to DataBase.

Now I want to run few instances of this application on Google Cloud. But I cannot get some of steps I should do. First of all I found that Google not support Java 8. I can refactor and compile on Java 7. But the next problem I not see any docs how to run jar file. What service should I check? The search pass me to https://cloud.google.com/appengine/docs/java/quickstart#before-you-begin but this manual actually not helps, because I have jar file, but there is MAVEN plugin used to deploy Java Servlet application. I do not need web server. Is it possible to get ssh console and run application like java -jar, use linux chron like on usual server? Or I should use Maven plugin only, to deploy, even if I not need Web Server (Servlet Container)?

Thanks.

Sounds like you're looking at the AppEngine Classic documentation where you'll likely want the AppEngine Flexible (ManagedVM) runtimes.

AppEngine Classic doesn't run Java applications, it is a Java web service (think Jetty/Tomcat).  It uses a web.xml to determine which classes that extend HTTPServlet handle which requests.

Actually, on second thought, I think Compute Engine could actually be what you want instead of ManagedVM.  It's been a while since I dug into the differences.

Yes, right. I'll dive deeper to Compute Engine. Thanks.
