分级误差为2.2.1

Question

Error:A problem occurred configuring root project 'Scanner'.

什么是问题？如何解决这个问题？

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {
    jcenter()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

Answer 1

如果您在代理后面，请尝试Gradle代理配置。从您发布的错误日志来看，gradle似乎无法解析地址。确保gradle能上网。

另外，您可以尝试在jcenter()中进行以下更改。

buildscript {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

allprojects {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

这多次解决了这个问题。
