错误信息

解决办法

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'io.fabric.tools:gradle:1.24.1'
    }
}

改成

buildscript {
    repositories {
        maven { url 'http://s3.amazonaws.com/fabric-artifacts/public' }
    }
    dependencies {
        classpath 'io.fabric.tools:gradle:1.24.1'
    }
}
