rianadon / javaVSCode

Extension for java development on VSCode

Java Debugger

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

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.

E.g. configure the tasks.json file as follows and use run the build task. (note: if there are no errors displayed in the 'Tasks' output window, then there are no errors)

{
    "version": "0.1.0",
    "command": "javac",
    "isShellCommand": true,
    "showOutput": "always",
    "isWatching": true,
    "suppressTaskName": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"]
        }
    ]
}

Example 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
    "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
}

Issues and Feature Requests

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

Requirements

• JDK is installed (version 1.7.0 and later)

• Path to jdk is configured in launch.json
