Android 无法获取未知属性'；文件'；

在Android studio gradle版本中

distributionUrl=https\://services.gradle.org/distributions-snapshots/gradle-4.5-20171123235935+0000-all.zip

classpath 'com.android.tools.build:gradle:3.1.0-alpha04'

它得到了这个错误

Error:Could not get unknown property 'manifestFile' for task ':backend:generateDebugRFile' of type com.android.build.gradle.internal.res.GenerateLibraryRFileTask.

---

尝试改变GoeLLE、Studio版本等，不影响

首先，定期使用预发布（Alpha）软件的注意事项：如果你不需要使用Alpha进行任何特定的原因，请考虑使用稳定的版本。现在这意味着

• Android Studio 3.0.1
• 3.0.1（也称为com.android.tools.build:gradle:3.0.1）

这可能是因为

3.1.0-alpha04

插件删除了对

manifestFile

的支持，而您使用的其他插件仍然依赖于此。毕竟，该工具团队在3.0中使用了类似名称的

manifestOutputFile

我试着用它来建立一个项目

• 格拉德尔区4.4-rc-3
• Android Gradle插件3.1.0-alpha04
• Fabric Gradle插件1.25.0

应用了fabric插件并得到一条与您发布的错误消息非常相似的错误消息：

Crashlytics集成也有类似的问题，我发现需要添加

crashlytics{instantAppSupport true}

这是必要的，即使我没有使用即时应用程序

从

中找到Alpha版本意味着存在问题。您可以使用稳定的版本。distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip&classpath'com.android.tools.build:gradle:3.0.0'使用稳定的

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

@IntelliJAmiya，这是不起作用的。我正在尝试将android studio降级为稳定版本。@Fr099y好的。试试看，修好了吗？我在最新的AS 3.0.1上遇到了问题
