java - 如何使用JPDA调试jmeter-server？

Question

我正在为 JMeter 开发插件，我想在运行时从 Intellij IDEA 连接到 jmeter-server。 我已将以下字符串添加到 jmeter.bat:

set JVM_ARGS=-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=1099, suspend=n

但是当我尝试连接时，收到以下错误:

Listening for transport dt_socket at address: 1099
java.lang.NoClassDefFoundError: suspend=n
Caused by: java.lang.ClassNotFoundException: suspend=n
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: suspend=n.  Program will exit.
Exception in thread "main" errorlevel=1

我已经在同一台计算机上启动了 jmeter 和 jmeter-server，但为 jmeter-server 指定了端口。你能解释一下，我做错了什么吗？

正如我所说，我尝试删除 JVM_ARGS 中的额外空间，但仍然出现错误:

    Found ApacheJMeter_core.jar

我错过了什么吗？

挂起参数之前有一个额外的空格，这会导致 JVM 将其解释为第一个非选项参数(即主类名)。

尝试将上面的行替换为:

set JVM_ARGS=-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=1099,suspend=n
