This demo is intended to be used to demonstrate how to debug a Java application, built into a native executable, using GraalVM VS Code Extension Pack for Java.

1. Linux OS with GDB 10.1
2. Visual Studio Code
3. GraalVM Extension Pack for Java: Open Visual Studio Code, navigate to Extensions activity panel in the left-hand side Activity Bar (or use the Ctrl+Shift+X hot keys combination). Search for “GraalVM” in the search field. Find "GraalVM Extension Pack for Java", press Install. Reload will be required.
4. GraalVM runtime environment in VS Code: Navigate to Gr activity panel in VS Code and install some of the latest GraalVM Enterprise Edition versions available from the list.
5. Native Image: Upon GraalVM's installation completion, the “Install Optional GraalVM Components” window pops up in the right bottom corner. Install Native Image.

1. Clone Download or clone the GraalVM Demos repository:

   git clone https://github.com/graalvm/graalvm-demos

2. Open the demo folder, graalvm/demos/javagdbnative, in VS Code.

3. Open VS Code Terminal window and run following command:

   mvn -Pnative -DskipTests package

The mvn -Pnative -DskipTests package command will package a Java application into a runnable JAR file, and then build a native executable of it.

1. Select Run and Debug activity panel in VSCode
2. Add a new launch configuration named Native Image: launch into launch.json which should look like this:

   {
       "type": "nativeimage",
       "request": "launch",
       "name": "Launch Native Image",
       "nativeImagePath": "${workspaceFolder}/target/javagdb",
       "args": "100"
   }

3. Then run debugger using Launch Native Image from RUN... menu. It will start debugging a native image binary in VSCode using Java source code.
