I am migrating the maps I have made with the “Charts” addon to the commercial version of the “Maps” addon, but when I run the application I run into the following error:
Compiling module com.myproject.web.toolkit.ui.AppWidgetSet
[ERROR] Hint: Check that your module inherits ‘com.google.gwt.core.Core’ either directly or indirectly (most often by inheriting module ‘com.google.gwt.user.User’)
Task :app-web-toolkit:buildWidgetSet FAILED
Execution failed for task ‘:app-web-toolkit:buildWidgetSet’.
Process ‘command ‘C:\Program Files\Java\jdk1.8.0_231\bin\java.exe’’ finished with non-zero exit value 1
I have been seeing forums for a week that may have changes depending on the version, so I am currently using the Java 8 version.
Any idea how to fix it?
