这是我第一次使用Android Studio，如果这是一个业余错误，请原谅。因此，我尝试按照此处的Google教程创建WearOS表盘：https://codelabs.developers.google.com/codelabs/watchface/index.html#0
但是，当我将项目下载并加载到Android Studio中并尝试与Gradle“同步”项目以使其生成并加载模块时，出现此错误：
错误：无法获得根项目的未知属性'com' 类型为org.gradle.api.Project的“ watchface-master”。
这是build.gradle文件：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
我试图在依赖项的类路径中更改gradle版本，但这没用
这是Android Studio中的事件日志：
08:59 Gradle同步从单变量同步开始
08:59 Gradle同步失败：无法获取未知属性'com' 根项目“ watchface-master”，类型为org.gradle.api.Project。 （689 毫秒）
08:59 NDK分辨率结果：项目设置：Gradle模型 版本= 5.4.1，NDK版本为未知
按照@guido的有关sdk版本更改的说明进行操作后，模块已成功构建，但仍然保留了原始的同步错误。有关同步的以下错误消息：

我尝试自己同步项目，一段时间后它就起作用了！您如何将项目导入android studio？尝试下载所需的zip并将其解压缩到同一文件夹（例如，Downloads）。然后“文件”->“打开”并导航至下载，项目名称将带有绿色标志。签出，然后尝试将build.grade中的构建工具版本更改为28.0.3，并将各自文件夹中5个模块的目标和编译版本更改为28。还将那里的依赖项更新为Studio所建议的内容（将光标设置为版本号，然后会出现左侧的黄色符号，单击它会建议更新。在此处，您可以将“编译”更改为“实现”，然后更改其他划掉的命令）。还要在主build.gradle文件的jcentre（）下添加google（）。然后，当我这样做时，它出现了一些错误，我可以通过在主菜单选项卡中按“重构”并按“迁移到AndroidX”来解决（只需选中“执行重构”，不必担心Studio）。然后编译！奇怪的是，该项目使用的是非常旧的版本。您最初的错误可能是由于导入问题，也可能是由于依赖性。 希望能帮到您!!!!
答案 1 :(得分：0)
您需要导入该项目，而不是打开该项目
在新项目选项中，使用Import project (Gradle, Eclipse, etc.)代替Open existing Android Studio project打开项目
答案 2 :(得分：0)
即使更新某些依赖项后，由于某些Gradle文件的弃用，我也遇到了相同的错误。我的解决方案是：
这对我有用，希望对您有用。
