GWT Super Dev Mode not compiling latest sources - maven

Question

I have a GWT project using GWT 2.7.0 and am using maven. The app is compiling and running correctly, however, I am struggling to get GWT's Super Dev Mode to work correctly. When I start Super Dev Mode with
mvn gwt:run-codeserver
Super Dev Mode starts correctly, compiles, and the latest changes ARE shown in the browser. However, when I press the compile bookmarklet to recompile the GWT code, the recompile completes correctly and the browser refreshes but does NOT include any subsequent changes I've made to the client/GWT java files.
When starting GWT Super Dev Mode it appears to copy the source files (.java files) from src/main/java into maven's build folder (target) and it appears to be compiling from source files in the target folder rather than those in src/main/java. I've tested this by manually copying a java file I've made changes to from src/main/java into the target folder, and then hitting the compile bookmarklet. When I do this the recompile succeed as before, and the latest changes are shown.
I am assuming I have either missed some configuration that will copy src/main/java into the target folder whenever I hit the compile bookmarklet, or I have misconfigured Super Dev Mode to compile from the target folder when it should be compiling from sources in src/main java
Any help to understand how it should function and resolve this would be appreciated.

Answer 1

https://tbroyer.github.io/gwt-maven-plugin/codeserver.html
Starting with GWT 2.7, you should set the launcherDir property to get recompile on reload. The property should point to a folder that your web server / servlet container will look into for web resources, so that the *.nocache.js file generated by the CodeServer can be loaded by your web browser.

Answer 2

Some time I face that problems and I follow those steps:
1. Clear browser cache
2. Clear GWT cache located in temp folder (in USER_HOME folder, it's based on your OS) and in gwt-unitCache folder (in launcherDir)
