找不到com.android.tools.build:gradle:3.0.1

Question

当我尝试使用gradle包装器构建我的项目时,我收到此错误:

./gradlew

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all files for configuration ':app:classpath'.
   > Could not find com.android.tools.build:gradle:3.0.1.

同一个项目在Android Studio中构建正常.

我已经检查了这个和这个,但我使用gradle包装器版本4.1,添加了google()存储库,甚至尝试过设置android.enableAapt2=false.还有其他提示吗？谢谢.

我的根build.gradle文件:

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

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

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

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

我的gradle-wrapper.properties档案:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

更新:加布里埃尔是对的.我还要在以下位置添加存储库app/build.gradle file:

...
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}
...

我想我很困惑这个stament "要添加这些图书馆之一到您的构建,包括顶层的build.gradle文件谷歌的Maven仓库"在这里.

只是想留下额外的小费.当我安装Android Studio时,我在某处读到了建议保留此配置(带有'+'符号)

build.gradle(项目)

dependencies {
        classpath 'com.android.tools.build:gradle:+'
        .....
        #more lines here
}

但是,我使用的项目使用旧版本的gradle,此行始终请求最新版本.我花了一段时间来搞清楚.
