1、編譯版本超出AS版本

控制臺右邊報錯:

Unable to resolve dependency for ':app@debug/compileClasspath': Could not find any version that matches com.android.support:appcompat-v7:29.+.
翻譯:無法解決':app@debug/compileClasspath'的依賴項(xiàng):找不到任何與com.android.support:appcompat-v7:29.+匹配的版本。
解決該問題的方法:降低compileSdkVersion的SDK版本,一般改為27以下就好了。
