Google Chrome Developer Tools for Java

This project provides debugging tools for developers writing applications that run on Google Chrome or its open-source version Chromium or any V8-based application. The tools enable you to debug JavaScript inside these browsers over the TCP/IP protocol. If you are looking for information on the Google Chrome browser built-in Developer Tools, please have a look at this official primer.

This project comprises:

• A ChromeDevTools SDK that provides a Java API that enables a debugging application to communicate with a Google Chrome browser from the localhost using the TCP/IP-based Google Chrome Developer Tools Protocol or WebKit Remote Debugging Protocol.
• An Eclipse debugger that uses the SDK. This debugger enables you to debug JavaScript running inside Google Chrome tabs from the Eclipse IDE.

As the SDK and Eclipse debugger are written in Java, this project is of most benefit to developers who use Java tools for debugging web applications inside Google Chrome. You can use the SDK to write your own debugger that uses the protocol to communicate with Google Chrome.

What's new

Version 0.3.4 has a conspicuous bug in Debugger that stops debugging Google Chrome/Chromium when "Network console" is disabled.

Version 0.3.4 has been released. What's new? How to install?

Version 0.3.2 has been released. What's new? How to install?

Using the Eclipse Debugger

Prerequisites:

• Eclipse version 3.5 or later (minimal configuration is Eclipse Platform).
• Google Chrome (or Chromium) version 3.0.189.0 or later (the latest version can be retrieved from the Dev Channel). See version compatibility table for details.

Installation:

• Download Debugger or build it from sources.

How to Debug:

1. Close all windows of Google Chrome or Chromium browsers. (Debug command-line option doesn't work for secondary browser processes).
2. Start the Google Chrome (or Chromium) browser as:
   chrome --remote-debugging-port=9222 (or some other debugger port of your choice.)
   Make sure your firewall blocks incoming connections to the chosen port from other machines. Open the URL you want to debug.
3. Start Eclipse and create a new debug configuration (under Run | Debug Configurations...) from the "WebKit Protocol" configuration type (you might need to switch to the Debug perspective first):
   
   
   
   
   
   
   
   Then specify the debugger port you have chosen, in the "Remote" tab. Also you need to select a proper WebKit protocol version in Wip backend field.
4. Start debugging. When prompted, select the tab to debug and click the "OK" button.
5. In a short while, you will see the browser script sources in a new project.
