1. debug 相关

1.1 问题： 

Intellij Debugger slow: Method breakpoints may dramatically slow down debugging

解答：

From the JetBrains Team: "Method breakpoints will slow down debugger a lot because of the JVM design, they are expensive to evaluate. Remove method breakpoints and consider using the regular line breakpoints.". See more.

To make the long story short, it seems that the root issue is that Method Breakpoints are implemented by using JPDA's Method Entry & Method Exit feature. This implementation requires the JVM to fire an event each time any thread enters any method and when any thread exits any method.

3. idea 社区版问题

3.1  报错： blocking external HTTP repositories?

maven 高版本需要仓库的域名是https, http 会阻塞住。
