Debugging in Eclipse GWT

Question

Since yesterday I've been working on an existing GWT project. My problem however is that I can't debug in Eclipse. It simply won't break in my breakpoints.

I've seen other people with the same issue:

• GWT 2.0 Eclipse Breakpoint Not Working
• Why when starting GWT in debug mode, my break points don't break
• Why are my breakpoints ignored with GWT, Eclipse, and Java 1.6.0_14?
• GWT SuperDevMode breakpoints not working

And I've also looked at some tutorials:

• GWT development mode in Eclipse
• GWT Debugging

I've tried all kind of different things based on these sites, but none of them seem to work. Some things I've tried:

• using FireFox instead of Google Chrome
• using jdk1.8.0_72 instead of jdk1.7.0_79
• putting gwt-dev-2.7.0.jar at the top of my Classpath User Entries (instead of somewhere in the middle)
• Adding any combination of the following Arguments: -bindAdres my.ip.adres; -gen my_path; -eclipse (-eclipse isn't a valid argument btw..).

My current configurations:

Main-tab:

Project:
    user-testwar
Main class:
    com.google.gwt.dev.DevMode

Arguments-tab:

Program arguments:
    -logLevel INFO
    -port 8888
    -war C:\Users\...\user-testwar\target\UserTestWar
    -superDevMode
    -remoteUI "${gwt_remote_ui_server_port}:${unique_id}"
    -codeServerPort 9997
    my.package.gwt.udf.viewer.TestWarProject
VM arguments:
    -Xmx512m

Classpath-tab:

Bootstrap Entries:
    JRE System Library [JavaSE-1.6]
User Entries:
    gwt-dev-2.7.0.jar
    java - \user-testwar\src\main\
    gwt - \user-testwar\target\generated-sources\
    java - \user-jar\src\main\
    gwt - \user-jar\target\generated-sources\
  > user-testwar (default classpath)
        user-testwar
        Maven Dependencies
        gwt-user.jar
        gwt-codeserver.jar
        gwt-dev.jar
        validation-api-1.0.0.GA-sources.jar
        validation-api-1.0.0.GA.jar

So, anyone has any (other) ideas to fix the debug issues with Eclipse and GWT?

EDIT:

When I put a breakpoint in our RemoteService implementation class it does break there. But the breakpoints of my widgets / pages in the user-jar project and in the main code of my user-testwar project (where I want to debug) are ignored..

Answer 1

If you want to debug your GWT application in Eclipse and you are using SDM, you need the SBDG plugin.

The SDBG-plugin can be downloaded here: https://sdbg.github.io/

Otherwise, when using SDM, you have to debug in the browser.

Another solution is to use Intellij Ultimate edition, which offers a JavaScript debugger. You need the Ultimate edition in Fact that the GWT facet is not part of the Community edition.

Update:

Starting with version 3.0 of the GWT Eclipse plugin, the SBDG-Plugin is integrated into the GWT plugin and makes it quite easy to debug a GWT application.
