Sounds interesting, I'll definitely give it a try, thank you - and for the 
gradle file, I really need a production grade gradle example

 Hi Jasper

 I'll be just glad if my current progress saves someone's time.
 I progress on step by step basis, so far I succeeded in Eclipse build 
 and debugging.

 Most of my problems were caused by combination of JDK11+ (namely 
 modules) + Gradle + Eclipse + Eclipse GWT Plugin. 

 Reason: GWT SDK gwt-dev.jar contains lot of classes that must not be 
 visible to Eclipse compiler, but in fact they are, causing dreaded "The 
 package org.w3c.dom is accessible from more than one module: , 
 java.xml" error.
 When `gradle build` is issued in command line the gwt-dev.jar from the 
 maven repository is linked, it contains exactly essential google classes 
 and nothing more. Thus the build succeeds.

 But when you import such project in Eclipse under JDK11+ (I use JDK17) 
 and select a GWT SDK there're lots of build errors caused by "The package 
 is accessible from more than one module"

I had a similar concern, as before we both SuperDevMode and the app in the 
same Java process.
After the switch, we need to start the codeserver and then the app, via 
Tomcat. But, things went well, because:

   1. You don't have to start your app in the build tool and connect 
   remotely. The codeserver will write its files to the same place as the 
   regular compilation would, and you can start your app in a debug session in 
   Eclipse. We're using the built-in Tomcat server (with Eclipse WTP). Just 
   make sure that after starting the codeserver, you have your workspace 
   refreshed, so Eclipse can publish it accordingly (that's why we wrote the 
   script, as mentioned in the previous post)
   2. Starting the codeserver is actually slower than the app (at least for 
   us, and the app is huge). When you debug the app, you'll eventually do an 
   incompatible change that needs to restart the app. When using the 
   codeserver as a separated process, it stays there, in the same place, even 
   when you restart the app. IMO, this ended up being more productive than the 
   previous setup
   3. If GWT 3 is ever released, having a separated codeserver will be the 
   only option
