Beginners diao wire questions about breakpoints and namespace

I added a breakpoint , but they can not hit.
I know the menu bar "Debug " and " Options - Debugging - General" , uncheck " Require source files to exactly match the original version " , you can change the breakpoint is hit problems . However, I do not know why cause the source file does not match the original version , how to match up . Seeking answers.


create a new project , using someone else's template , but do not like the original namespace directly modify the namespace name ( instead scs.controllers) , set breakpoints and compiled , and why it is still under the original type of the class "ecmall.controllers.visitor".
