[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'
I want to upgrade my application from Java 1.8 to jdk17. I'm getting the above mentioned error while compiling my code using jdk17. I have used <inherits name='com.google.gwt.user.User'/> in my app.gwt.xml file. GWT Version used - 2.5.1 Build tool - ANT Note : I have used gwt-dev.jar, gwt-user-2.5.1.jar, gwt-servlet.jar in my .classpath file. Build failure is happening in my 'compile-gwt' build step.
