JAR d'agent introuvable ou aucun attribut de classe d'agent

Question

// Correction: Ce n'était pas une erreur à cause du code. C'était à cause de l'IDE.

J'ai juste essayé de faire une injection pour un jeu appelé Minecraft. Mais j'ai un problème. Ce n'est pas en mesure de charger l'agent.

Voici l'exception: Exception in thread "main" com.sun.tools.attach.AgentLoadException: Agent JAR not found or no Agent-Class attribute at sun.tools.attach.HotSpotVirtualMachine.loadAgent(HotSpotVirtualMachine.java:117) at com.sun.tools.attach.VirtualMachine.loadAgent(VirtualMachine.java:540) at pw.razex.injectionclient.Injectable.main(Injectable.java:55)

Et mon code:

AgentLoader [AgentClass]

public class AgentLoader { 

public static void agentmain(String agent, Instrumentation instrumentation) { 
    try { 
     Class[] loadedClasses = instrumentation.getAllLoadedClasses(); 

     File agentFile = new File(AgentLoader.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath()); 
     agentFile.deleteOnExit(); 

     for(int i = 0; i < loadedClasses.length; i++) { 
      Class loadedClass = loadedClasses[i]; 
      if(loadedClass.getName().equals("net.minecraft.client.Minecraft")) { 
       LaunchClassLoader launchClassLoader = (LaunchClassLoader) loadedClass.getClassLoader(); 
       launchClassLoader.addURL(AgentLoader.class.getProtectionDomain().getCodeSource().getLocation()); 
       launchClassLoader.loadClass(MainGui.class.getName()).newInstance(); 
      } 
     } 
    } catch (Throwable e) { 
     e.printStackTrace(); 
    } 
} 

}

Classe principale:

public class Injectable { 

private static VirtualMachineDescriptor minecraftProcess; 

public static void main(String[] args) throws Throwable{ 
    OSUtil.initOS(); 

    if(OSUtil.osType != OSUtil.OSType.WINDOWS) { 
     System.out.println("[X] Invalid OS [" + OSUtil.osType.name() + "]"); 
     System.exit(-1); 
    } 

    File sourceFile = new File(Injectable.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath()); 
    File tempAttachFile = File.createTempFile("lgt", ".dat"); 
    Files.copy(sourceFile.toPath(), tempAttachFile.toPath(), StandardCopyOption.REPLACE_EXISTING); 

    System.out.println(new File("attach.dll").exists()); 

    if (System.getProperty("java.library.path") != null) { 
     System.setProperty("java.library.path", new File("attach.dll").getAbsolutePath() + System.getProperty("path.separator") + System.getProperty("java.library.path")); 
    } else { 
     System.setProperty("java.library.path", new File("attach.dll").getAbsolutePath()); 
    } 

    Field field = ClassLoader.class.getDeclaredField("sys_paths"); 
    field.setAccessible(true); 
    field.set(null, null); 

    System.loadLibrary("attach"); 

    if(VirtualMachine.list().size() == 0) { 
     System.out.println("[X] No injectable process found"); 
     System.exit(-1); 
    } 

    List<VirtualMachineDescriptor> virtualMachineDescriptors = VirtualMachine.list(); 
    for(VirtualMachineDescriptor virtualMachineDescriptor : virtualMachineDescriptors) { 
     if(virtualMachineDescriptor.displayName().startsWith("net.minecraft.client.main.Main")) { 
      minecraftProcess = virtualMachineDescriptor; 
      VirtualMachine virtualMachine = VirtualMachine.attach(minecraftProcess); 
      virtualMachine.loadAgent(tempAttachFile.getAbsolutePath()); 
      System.out.println("[O] Attached to minecraft"); 
     } 
    } 

    if(minecraftProcess == null) { 
     System.out.println("[X] Minecraft is not started yet."); 
     System.exit(-1); 
    } 
} 

}
