AgentInitializationException：代理 JAR 已加载但代理未能初始化 - 尝试注入 JAR 文件

Question

All other questions on the subject did not solve my problem.

Injector:

VirtualMachine vm = VirtualMachine.attach(pid);
vm.loadAgent(new File("inject.jar").getAbsolutePath());
vm.detach();

inject.jar has the correct manifest and everything. Inject code:

public static void agentmain(String[] args) {
    System.out.println("test");
    // also tried: writing a file to an absolute location,
    // and adding Instrument to the signature above
}

I get the error mentioned in the title when I run the injector.

inject.jar manifest:

Manifest-Version: 1.0
Agent-Class: Main
Can-Redefine-Classes: true
Can-Retransform-Classes: true

Answer 1

我发现问题出在我的 agentmain 函数中，它使用String[]而不是String作为第一个参数。
