您的gradle文件中的存储库通常存在问题。
对我来说,修改build.gradle是这样的:
buildscript {
repositories {
mavenLocal()
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
因此,当您添加google()时,它应该可以正常工作。

buildscript {
repositories {
jcenter()
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
在google()
和同步项目中添加buildscript()
。
