After the Android Studio plugin is upgraded, the kotlin jdk version conflicts
After upgrading some plug-in versions today, I couldn’t compile. I found that kotlin jdk 1.8.20 and kotlin jdk 1.6.21 conflicted repeatedly. I found many methods on the Internet, but they didn’t work. It took a lot of time to solve it. I hope it can help those who report the same error. classmate
