问题
I am developing client side of my application using IntelliJ IDEA. For debugging I need to run multiple clients.
I guess running same projects in different windows is not possible with IntelliJ IDEA. So how do I run multiple clients for debugging?
回答1:
You can run or debug the same Run/Debug configuration in IntelliJ IDEA several times if you enable the Allow parallel run checkbox.
You will see a tab per instance in the Run or Debug tool window.
In the previous IDE versions this checkbox was called Single instance only and its effect was reversed.
