gwt maven plugin deploy to standalone tomcat not loading
I'm using the latest gwt maven plugin (https://tbroyer.github.io/gwt-maven-plugin/index.html) to compile a multi module GWT project and deploy it to tomcat 9. I am also using intellij 14 as my IDE. It's a client app only ie. no server/servlet. When I build via the IDE gwt plugin and zip up and deploy that output to tomcat my app works fine.
However, using the maven plugin, everything compiles ok and the contents of the war look fine to me. The war deploys ok to tomcat, but I simply see a blank page when I try to load it on my browser (latest chrome edition).
I'm running dev tools and jscript console and there are no errors being reported, network view, shows the content downloading ok. I've set break points in my nocache js files and stepped through it with no problems. Below is my pom. I'd appreciated any insight / help with this as it's been bugging me for days..

For anyone that is interested I got the maven build working on the multi module gwt project. See the following pom (dashboard) which is my app which inherits other modules.

I have to include the build resources entries on this pom and my inherited projects to manually include the public directory, not sure why, this appears to a quirk with the plugin.
