Golang断点在IntelliJ IDEA 2016.1.1中不起作用

I was debugging a GoLang program. I set break points and run the debugger. But the break points only works the first time I run the debugger and failed in the second, the third, and all following debugging whatever I do. I cancelled them and reset them, I close the debugging window and open a new one, I change the settings in the "Breakpoints" tool window. All these didn't work at all. What's the problem?

Update, this has been fixed in the latest release of the plugin, please check it out

This is a well known problem and it lies in delve not the plugin itself. Please see this this issue for further reference.
