问题
I was debugging a GWT in Eclipse using "Super Dev Mode", Java 8, and Eclipse Photon. I've put breakpoints in the client side of the code, but none of them seem to trigger.
I'm reading the documentation, but it appears to relate to "Legacy Dev Mode" debugging. http://www.gwtproject.org/doc/latest/DevGuideCompilingAndDebugging.html
Does anyone have any recommendations to "step through" client side code with "Super Dev Mode"?
回答1:
If you use GWT's Super Dev Mode, debugging is done completely in the browser and the Super Dev Mode provides sourcemaps to know where in your "Java"-code you currently are. You have to use e.g. Chrome's Developer-Tools and set breakpoints there.
Here is a tutorial how to use the Debugging-Feature of Chrome: https://developers.google.com/web/tools/chrome-devtools/javascript/

Use the GWT eclipse plugin by Branflake : https://github.com/gwt-plugins/gwt-eclipse-plugin
Check out his youtube tutorial videos linked from the github page : https://www.youtube.com/watch?v=DU7ZQVLR5Zo&list=PLBbgqtDgdc_TqzA-qXrjgTFMC_6DKAQyT
With this plugin you can debug from within Eclipse with SuperDevMode.
Another option is to use the Ultimate (not free) version of IntelliJ. This has GWT support built in including debugging from within the IDE.
