尝试调试时出现Eclipse JDWP错误 [英] Eclipse JDWP error when trying to debug

问题描述

尝试在eclipse中调试本地Java应用程序时出现以下错误.

I get the following error when trying to debug a local java application in eclipse.

FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ERROR: transport error 202: connect failed: Connection refused
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690]

我读到它可能是由于某些东西使用了与一个eclipse想要用于调试的端口相同的端口引起的，但是我如何确定端口号.我在错误日志或首选项中找不到任何内容.

I read that it might be caused by something using the same port as the one eclipse wants to use for debugging, but how do I determine the port number. I couldn't find anything in the error log or the preferences.

有什么想法吗?

推荐答案

我遇到了同样的问题，结果发现我在jdwp调试字符串中指定了server = n参数.事实证明，如果我们在调试连接字符串中指定server = n，它将尝试连接/连接到该端口，而不是侦听该端口.切换到 server = y 解决了我的问题.它记录在 官方jpda文档.

I ran into the same issue and it turns out I was specifying server=n parameter in the jdwp debug string. It turns out that if we specify server=n in the debug connection string, it'll attempt to attach/connect to that port instead of listening on it. Switching to server=y solved my issue. It's documented in the official jpda documentation.
