Intellij IDE Installation Golang plugin error in Go SDK

This is a creation in Article, where the information may have evolved or changed.

Many Java students use idea, of course, can also use the Gogland directly at least now or free. No one knows when it will be charged again. So we chose idea to support the development of Golang using plug-in methods. Old idea can easily appear "the selected directory is not a valid home for Go SDK", such as my version 15.0.1. View the plugin documentation.

The discovery plugin already does not support version 15. Just upgrade idea, how to upgrade? How to crack? Please own Baidu to put! Theoretically 15 can support Golang 1.4, but who is still using it?
