Debug/run standard java in Visual Studio Code IDE and OS X?

Tags:

Love the light-weight Visual Studio Code in OS X. Have always wanted the ability to write, debug and run standard java (NOT javascript) from VSC in OS X. Found the following extension which allows you to debug and run java from VSC:

https://marketplace.visualstudio.com/items?itemName=donjayamanne.javadebugger

Followed the directions as best as I could. Trying to run my java app, and I am getting a bunch of "error: cannot find symbol" errors in the debug-console window when I run my java app in VSC from OS X. App runs great in eclipse. What am I missing in either VSC or somewhere in OS X so I can properly run java code from VSC in OS X?

There is a much easier way to run Java, no configuration needed:

  1. Install the Code Runner Extension
  2. Open your Java code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.
