Ifz*_*mar 3 android gradle android-studio wear-os
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 Google 的教程创建一个 WearOS 表盘： https: //codelabs.developers.google.com/codelabs/watchface/index.html#0
但是，当我下载项目并将其加载到 Android Studio 中并尝试将项目与 Gradle“同步”以便构建并加载模块时，我收到此错误：
错误：无法获取 org.gradle.api.Project 类型的根项目“watchface-master”的未知属性“com”。
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()
}
我尝试更改依赖项中类路径中的 gradle 版本，但这不起作用
这是 Android Studio 中的事件日志：
08:59 Gradle 同步从单变体同步开始
08:59 Gradle 同步失败：无法获取 org.gradle.api.Project 类型的根项目“watchface-master”的未知属性“com”。（689 毫秒）
08:59 NDK 解决结果：项目设置：Gradle 模型版本=5.4.1，NDK 版本未知
按照 @guido 关于 sdk 版本更改的说明进行操作后，模块已成功构建，但原始同步错误仍然存在。有关同步的以下错误消息：
groovy.lang.MissingPropertyException: Could not get unknown property 'com' for root project 'watchface-master' of type org.gradle.api.Project.

即使更新了一些依赖项后，由于某些 Gradle 文件已被弃用，我也遇到了相同的错误。我的解决方案是：
这对我有用，希望对你也有用。
