IntelliJ setup with Java 8 + GWT 2.8.2 and Sencha 4.0.2

My setup details are:

IntelliJ 2018.1.3

GWT 2.8.2

GXT 4.0.2

Java 1.8.0.161

Apache Maven 3.5

I am unable to bring up my application, although maven build is done successfully and also the server comes up successfully.

I get below error when I try to hit the URL for accessing the application:

ERROR: Unable to load module entry point class com.abc.pqr.Desktop(see associated exception for details)

Is there an issue with IntelliJ GWT Plugin? or IntelliJ Maven plugin?

I have installed GWTP Plugin from within IntelliJ Idea for my project.

Any inputs or directions to check what all settings would be of great help, stuck here for long.
