1、com.android.tools.build:gradle:7.0.3 > com.android.tools:sdk-common:30.0.3 > xerces:xercesImpl:2.12.0

• 解决方案：添加google()或mavenCentral()或jcenter() ` buildscript {

    repositories {
        google()
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.3"
  
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    } } ```
