android - Android Studio 中缺少 com.android.tools.build.gradle4.1

Question

这是我的 build.gradle 文件:

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

buildscript {

    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1'


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

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

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

这里是 gradle-wrapper:

我查看了目录 /home/xavi/android-studio/gradle/m2repository/com/android/tools/build/gradle/4.1/ 并看到我做 有一个 gradle 4.1 构建，但它不像其他的那样包含一个简单的 .jar。这是从官方 gradle 网站下载的完整内容。它包含许多可执行文件，但没有像其他文件那样标记为 gradle-4.1.jar。

编辑:将 classpath 更改为正确的行后，android studio 提示我将 gralde 更新到 4.4.1，并且我得到了回溯。

不要将 gradle 与 gradle 的 androd 插件 混淆。

改变:

classpath 'com.android.tools.build:gradle:4.1'

与:

 classpath 'com.android.tools.build:gradle:3.0.1'
