IntelliJ“调试信息不​​可用” - 如何修复？

Question

I have a Java Tomcat web application built in IntelliJ that calls code in another module called "Stuff". I've attached the source of the relevant code to "Stuff" so I can step into it and hit breakpoints, but I cannot see variables or their values. Watches don't work either. All I get is "Debug info unavailable".

How do I see the debug info?

Answer 1

I guess it's related to this question . Make sure the classes are compiled with the debug info. It can be tuned in Settings | Compiler or if you build from Ant, you need debug=on attribute for the javac task.

Answer 2

请使用以下选项进行编译：

javac -g:source,lines,vars
