Could not find com.android.tools.build:aapt2:3.2.1-4818971.

升级gradle后，apt取消了，

报错：

 Failed to capture snapshot of input files for task ':app:mergeDebugResources' property 'aapt2FromMaven' during up-to-date check

 Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.android.tools.build:aapt2:3.2.1-4818971.

找到解决办法：

在项目的gradle里面添加： google()谷歌库

allprojects {
    repositories {
        google()//新增的
        jcenter()
      
    }
