推荐答案

确保在Eclipse的vmargs中有 -Dcom.sun.management.jmxremote 。

Make sure you have -Dcom.sun.management.jmxremote in the vmargs of Eclipse.

您可以查看是否在此对话框中查找：帮助 - >关于 - >安装详细信息 - >配置。

You can find out whether you have looking in this dialog: Help -> About -> Installation Details -> Configuration.

eclipse.vmargs = ... 显示为Java VM传递的所有参数。

eclipse.vmargs=... shows all the arguments which were passed for the Java VM.

如果缺少此选项，则打开 eclipse.ini 并搜索 -vmargs <行/ code>。如果它不存在，请在最后添加：

If this option is missing, then open eclipse.ini and search for the line -vmargs. If it's not there, add it at the end:

  -vmargs
  -Dcom.sun.management.jmxremote

请注意，这些选项中的每一个都应该在不同的行上。

Note that each of these options should go on a different line.

确保 -vmargs 是文件中的最后一个Eclipse选项;下面的所有内容将被组合成一个VM的参数数组，并被Eclipse忽略。

Make sure that -vmargs is the last Eclipse option in the file; everything below will be assembled into an array of arguments to the VM and ignored by Eclipse.
