Gradle 3.0.0-beta1 构建问题
Gradle 3.0.0-beta1 build issue
我刚刚将 gradle 版本更新为
classpath 'com.android.tools.build:gradle:3.0.0-beta1'
将 android studio 更新到 3.0-beta1 后，我的 gradle-wrapper 是：
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip
问题是当我想 Gradle-同步项目时我遇到了这个奇怪的问题：

我检查了一切，它们看起来都很好，有人可以帮忙吗？
Build -> Clean project，然后
Build -> Rebuild project
3.0.0 中有一些已知错误，这个问题就是其中之一，实际上 android 工作室正在为 Linux OS 集成 Unix 文件系统（伯克利快速文件系统）它处于测试阶段……请暂时将您的工作室降级到 2.3.3 稳定版。
试试这个选项：
- 保留 Gradle 同步错误并清理项目
- 重建项目
- 现在同步Gradle现在
注：我也做了
invalidate and restart
在尝试之前
对我有帮助，希望对你也有帮助。
我在更新到 beta1 后遇到了同样的问题。
尝试在 SDK Manager -> SDK Tools 中将构建工具更新到最新版本。然后将 google maven 添加到您的 root build.gradle，如下所示：
allprojects {
repositories {
jcenter()
maven { url 'https://maven.google.com' }
}
}
这对我来说很有效
根据这个官方link这是已知问题。
Known issue: If you have an existing Android Studio project that's
using an alpha version of Android plugin 3.0.0 (such as 3.0.0-alpha9),
you may get the following error when you migrate to Android plugin
3.0.0-beta1 and sync your project: Gradle project refresh failed.
Solution: Resolve this issue by selecting Build > Clean Project from the menu
bar—you need to perform this action only once for each project. You
can then sync your project files with Gradle by clicking Sync Project
from the menu bar.
