找不到com.android.tools.build:gradle:3.0.0-beta2

我无法解决与gradle文件关联的问题。为了解决此问题，我下载了android studio 3.0 beta 6，其中未构建项目。在Android studio 2.3.2中，出现了以下问题

如何解决这个问题？我在stack上看到了许多解决方案，但无法解决此问题

您必须在顶级build.gradle文件的

buildscript

块中添加maven google：

buildscript {
    repositories {
       jcenter()
       ...
       // You need to add the following repository to download the
       // new plugin.
       maven { url "https://maven.google.com" }
    }
   dependencies {
       classpath 'com.android.tools.build:gradle:3.0.0-beta6'
       //...
   }
}

此版本的插件还需要gradle的更新版本。您必须更新

gradle wrapper.properties

中的

distributionUrl

，如下所示：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

同时删除.gradle和gradle文件夹并重新同步项目。缓存问题

我使用Android Studio 3.0 Beta2解决了这个问题。我刚刚更改了gradle依赖项，如下所示

顶级渐变依赖项

我刚把beta6换成beta2。我不知道它是怎么工作的，但它工作得很好

你有没有试过从classpath'com.android.tools.build:gradle:3.0.0'中删除beta2？没有。我没有试过。好的，你必须试一下。classpath'com.android.tools.build:gradle:3.0.0'我必须删除前一个并添加新的吗？你可以把这个：------------classpath'com.android.tools.build:gradle:3.0.0'我必须在哪里添加这些你的项目级gradlefile@Ghimire在您的顶级文件中。您只需添加另一份回购协议。您也可以使用最新的beta-6。@ND1010\您不需要在project build.gradle中添加此部分。由于buildscript块位于顶级文件中，所以只需使用它。@Ghimire在答案中有一个链接，其中包含有关迁移的所有详细信息。您还必须上传gradle版本
