在allprojects下的repositories闭包里面添加jcenter()和maven {url 'https://jitpack.io'}，具体可以看你的第三方框架需要添加什么仓库，大多数都只需要上面两个。

我的build.gradle（Project）完整内容如下：

buildscript {repositories {google()mavenCentral()}dependencies {classpath "com.android.tools.build:gradle:4.2.1"// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files}
}allprojects {repositories {jcenter()google()mavenCentral()maven {url 'https://jitpack.io'}}
}
task clean(type: Delete) {delete rootProject.buildDir
}

每个人都是有缺陷的，即使外表看起来很无暇。
