Gradle task tomcatRun is successful but webapp throws 404 error

Question

I have a Spring MVC webapp in Eclipse, which I build with Gradle. I'm using the Gradle Tomcat plugin as well.

When I run the Gradle tomcatRunWar task, everything works as expected and my webapp is responsive, as it should be. But when I run the Gradle tomcatRun task, although it appears to be successful and says "server is running at http://localhost:8080/", the webapp only throws 404 errors with the message "The requested resource is not available".

I then ran the Gradle task with the -i (info) and -d (debug) options and I see the following when I try to hit the server:

If I wait another 10 seconds or so, I then see this:

Your project layout needs to have at least src/main/webapp/WEB-INF/web.xml even if you declare another web.xml with tomcatRun.webDefaultXml.

Maybe you should remove tomcatRunWar.contextPath. I'm not sure if '' is deployed as the ROOT context. The 404 indicates, that the war is not deployed into the ROOT context. If you remove the contextPath you should be able to call http://localhost:8080/

We need to add Web Content folder in Deployment Assembly as Gradle doesn't configure it by default.
