无法为 org.gradle.api.Project 类型的项目“：app”获取未知属性“defaultCompileSdkVersion”

Question

我的应用程序的应用程序项目中不断出现此错误。

// Set property defaults after extension .gradle files.
    
    ext.cdvCompileSdkVersion = cdvCompileSdkVersion == null ? (
        defaultCompileSdkVersion == null
            ? privateHelpers.getProjectTarget()
            : defaultCompileSdkVersion
    ) : Integer.parseInt('' + cdvCompileSdkVersion)

Answer 1

您尚未在应用程序 gradle 中定义已编译的 sdk 版本并尝试获取它。 在你的项目 build.gradle 中声明 compileSdkVersion

 ext {
 compileSdkVersion = 28
 buildToolsVersion = '28.0.0'

 }
