错误：无法在Android Studio 3.4中解析依赖项。

androidgradleandroid-gradle-plugin

我之前使用的是 Android Studio 3.3，一切都很正常。但今天升级到 3.4 后，出现了这些错误。看起来问题源于 androidX 依赖库。这种情况在我依赖 androidX 的两个不同项目中也发生了。

我尝试过以下操作：

1. 清除并重新构建我的项目

2. 使缓存无效，并重启 Android Studio。

我该如何解决它。

- Nux

这可能是由于多种问题引起的。 1. 检查您的网络配置，可能您的网络正处于代理配置下 2. 打开新项目而不是现有项目，然后一切都可以正确编译，然后根据成功构建的项目配置旧项目 3. 如果启用了脱机功能，请禁用它。 4. 良好的网络连接也可能是答案。逐个尝试它们。因为这经常发生在我身上，上述其中一种方法总是帮助了我。顺便提一句，在每个步骤之后不要忘记“同步项目”。 - Jasurbek

你需要在你的项目的gradle.properties文件中添加以下规则：android.enableJetifier=true android.useAndroidX=true - madhu s

当我尝试将旧式即时应用程序转换为新的动态模块时，我遇到了相同的问题。它发生在已安装的功能中。这一定是Gradle中的错误。糟糕的实现。 - Gillis Haasnoot

@GillisHaasnoot解决了吗？ - Nux

是的，我已经进展了一点。我的问题在于，在动态模块中没有包含核心Android X库，因此出现了错误。因此，我创建了一个单独的“库”（不是动态模块），其中包含所有核心依赖项，例如： androidx.core:core:1.1.0-alpha05 androidx.fragment:fragment:1.1.0-alpha07 com.google.firebase:firebase-core:16.0.8 等等。我将该库包含在所有动态模块中。现在至少可以构建了。当然，我现在面临一组全新的完全不同的问题，我必须解决 :) - Gillis Haasnoot

当我升级到gradle 5.1.1时，我遇到了相同的问题。清除缓存无效。 - ScruffyFox

将以下内容添加到您的应用程序模块依赖列表中。

implementation 'androidx.drawerlayout:drawerlayout:1.0.0-alpha1'
implementation 'androidx.cursoradapter:cursoradapter:1.0.0-alpha1'

- Ranjan Kumar

谢谢您的回复。我已经添加了这些依赖项，但仍然面临同样的问题。 - Nux

我通过将 gradle-wrapper.properties 中的 distributionUrl 属性还原，解决了我的问题。

还原前：

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

返回

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip

还需要在 build.gradle 文件中将 gradle 依赖项恢复为先前的版本。

classpath 'com.android.tools.build:gradle:3.4.0'

返回

classpath 'com.android.tools.build:gradle:3.3.2'

现在我的项目很好。
