Cordova 无法获取未知属性'；ANDROID支持注释版本'；

我正在构建一个爱奥尼亚项目，并得到了这个错误

生成在1s内失败 错误：/Users/lalitkushwah/Desktop/BuildForIOS/platforms/android/gradlew:命令失败，退出代码1错误输出： 失败：生成失败，出现异常

• 其中： 构建文件“/Users/lalitkushwah/Desktop/BuildForIOS/platforms/android/app/Build.gradle”行：262

• 出了什么问题： 评估项目“：app”时出现问题。 无法获取类型为org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler的对象的未知属性“ANDROID\u支持\u注释\u版本”

这是package.json文件：

如果有人想解决这个问题，请提前感谢。

在platforms/android/project.properties中更改project.properties中的行

cordova.system.library.1=com.android.support:support annotations:$android\u support\u annotations\u VERSION

到

cordova.system.library.1=com.android.support:support注释：27+
