Question

Android Studio gradle版本中的

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

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

收到此错误

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

尝试更改gradle，Studio版本等不会影响

Answer 1

首先，关于使用预发布（alpha）软件的常规警告适用：如果您因任何特殊原因不需要使用alpha，请考虑使用稳定版本。现在这意味着

Android Studio 3.0.1
Android Gradle Plugin 3.0.1（a.k.a。com.android.tools.build:gradle:3.0.1）

有了这个......可能是3.1.0-alpha04插件删除了对manifestFile的支持，而你正在使用的其他插件仍然依赖于此。毕竟，工具团队did remove在3.0中具有类似名称的manifestOutputFile。

我尝试使用

构建项目

Gradle dist 4.4-rc-3
Android Gradle插件3.1.0-alpha04
Fabric Gradle插件1.25.0

应用了Fabric插件并收到了一条与您发布的内容非常相似的错误消息：

Answer 2

与Crashlytics集成有类似的问题，发现我需要添加

crashlytics { instantAppSupport true }

即使我没有使用Instant Apps，也需要这样做。
