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gradle从2.14.1升级到5.5.1，但它不允许。

以下是我得到的错误：

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

我在看一些旧的帖子，他们都详细说明了它的要求和项目，但奇怪的是，上面是空白的。

下面是我的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()
    }
}

我还在Android Studio>Properties>gradle>Use local gradle distribution中检查了gradle路径，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.

我做错了什么？

编辑:app>build.gradle:

Answer 1

这种依赖关系对应于Android gradle插件，而不是gradle本身。通常，Android gradle插件应该与Android Studio安装的版本号匹配（例如“3.4.2”）。

如果要更新Gradle本身，并且正在使用Gradle包装器，请更新Gradle/wrapper/gradle-wrapper.properties文件并编辑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，那么您不必做任何事情。您的项目将使用Android Studio设置中设置的gradle发行版来构建（在您的例子中是gradle 5.5.1)。

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:

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

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