Gradle 同步失败：找不到 com.android.tools.build:gradle:5.5.1

Question

所以，我遇到了一个奇怪的问题。我想将我的 gradle 从版本升级2.14.1到5.5.1它，它不会让我。

这是我得到的错误：

Gradle sync failed: Could not find com.android.tools.build:gradle:5.5.1.
            Searched in the following locations:
            - https://jcenter.bintray.com/com/android/tools/build/gradle/5.5.1/gradle-5.5.1.pom
            - https://jcenter.bintray.com/com/android/tools/build/gradle/5.5.1/gradle-5.5.1.jar

我正在浏览一些较旧的帖子，它们都详细说明了项目和项目的要求，但奇怪的是，上面是空白的。

这是我的build.gradle文件的样子：

// 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:5.5.1'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

我还仔细检查了 gradle 路径，Android Studio > Properties > Gradle > Use local Gradle distribution并将其设置为根gradle-5.5.1目录。

日志也没有帮助，它说的和上面一样：

2019-07-14 08:28:28,670 [thread 268]   INFO - e.project.sync.GradleSyncState - Gradle sync failed: Could not find com.android.tools.build:gradle:5.5.1.

我究竟做错了什么？

编辑： App > build.gradle:

Answer 1

This dependency corresponds to the Android gradle plugin, not Gradle itself. Typically, the Android gradle plugin should match the version number of your Android Studio installation (e.g. "3.4.2").

如果您想更新 Gradle 本身，并且您正在使用 gradle 包装器，请更新gradle/wrapper/gradle-wrapper.properties文件并编辑该distributionUrl行：

distributionUrl=https\://services.gradle.org/distributions/gradle-5.5.1-all.zip

如果您使用的是本地发行版，那么您无需执行任何操作。您的项目将使用在 Android Studio 设置中设置的 gradle 发行版（在您的情况下为 Gradle 5.5.1）构建。

编辑：似乎您的 build.gradle 文件也缺少google()存储库，如果您想使用 Android gradle 插件 3.4.2，它应该是什么样子：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
    }
}

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