import java.io.File; import java.io.IOException;

public class MinecraftLauncher{ public static void main(String[] args) throws IOException { File minecraftDir = new File('C:/users/username/minecraft'); File minecraftJar = new File(minecraftDir, 'minecraft.jar'); if(!minecraftJar.exists()) { System.out.println('Minecraft jar not found at '+minecraftJar.getAbsolutePath()); return; }

    ProcessBuilder pb = new ProcessBuilder('java', '-jar', minecraftJar.getAbsolutePath());
    pb.directory(minecraftDir);
    pb.inheritIO();
    Process process = pb.start();
