Project won't launch on Google Cloud Tools for Eclipse

Question

I've been trying to switch from the Google Eclipse Plugin to Cloud Tools for Eclipse, but I can't get a working launch configuration.

When I try to launch the project, the progress shows

Preparing launch delegate...: Launching delegate...

until it is finally aborted with

Server App Engine Standard at localhost (2) was unable to start within 240 seconds. If the server requires more time, try increasing the timeout in the server editor.

It's a maven project with Java on App Engine.

I have created a hello world maven project which launches fine.

When I examine the org.eclipse.wst.server.core/tmpX folder of the hello world project, I see various files and directories such as index.jsp, META-INF and WEB-INF, with WEB-INF/lib containing the maven dependency jars.

The same folder for my project contains only WEB-INF/classes which contains a wierd collection of files, including another WEB-INF with an empty lib

I'm running "Google Cloud Platform for Eclipse 4.5 and later 1.2.0.201706082053" on Oxygen Release (4.7.0), although the issues has always existed since I first tried to migrate end of 2016

Any suggestions?

tomcat unable to start within 240 seconds, go to server view Double click on your server, you can see Right corner of the server property Window max Time out option, change it to more the 240 second. and also check your configuration.
