Debugger for Java (Deprecated)

This extension is no longer maintained. It has been deprecated in favor of Java Debug Extension for Visual Studio Code

Big thanks to Faustino Aguilar for his continued effort in maintaining this extension.

Extension for VSCode with support for debugging Local variables, arguments, stack trace, step through, partial support for JavaFX, expanding values (Objects, Arrays) etc.

Requirements

NOTE: Path to JDK is configured in launch.json

• JDK is installed (version 1.7.0 and later)

Once installed, do remember to configure the JDK Path (in launch.json, else jdk path is assumed to be in the current path)

Ensure to compile the source code with debug symbols.

Debug info is needed to compile your code with debugging support, allowing to see variables value

You can configure the tasks.json file as follows and use run the build task. see -g flag in command.

{
    "version": "2.0.0",
    "tasks": [
        {
            "taskName": "Compile Java",
            "type": "shell",
            "command": "javac -g ${file}",
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

Then you need to add a launch configuration (launch.json):

{
    "name": "Java",
    "type": "java",
    "request": "launch",
    "stopOnEntry": true,
    "preLaunchTask": "build",                     // Runs the task created above before running this configuration
    "jdkPath": "${env:JAVA_HOME}/bin",            // You need to set JAVA_HOME enviroment variable
    "cwd": "${workspaceRoot}",
    "startupClass": "my.package.MyMainClass",     // The class you want to run
    "startupClassPathPattern": "src/main/java/",  // A pattern that matches the begining of your src path any paths after
                                                  // the pattern will be used to construct the classpath for your startupClass
    "sourcePath": ["${workspaceRoot}/src"],       // Indicates where your source (.java) files are
    "classpath": ["${workspaceRoot}/bin"],        // Indicates the location of your .class files
    "options": []                                 // Additional options to pass to the java executable
    "args": []                                    // Command line arguments to pass to the startup class
}

Features

Debug GUI applications.

Inspect variables, set breakpoints and see output in console.

Roadmap

• Enhancements to java debugger (pause and continue, etc)
• Debugging of Multi Threaded apps is possible but very flaky. The debugger could at times hang.
• Exceptions support #46

Known issues

• Sometimes debugger shows nothing, try to restart it. #27
• Debugging Android. To debug Android use this extension instead.
