在 com.android.build.gradle.AppExtension_Decorated 上找不到属性“xxxx" [英] Could not find property 'xxxx' on com.android.build.gradle.AppExtension_Decorated

问题描述

将这些行添加到我的 gradle 文件后，出现此错误:

I got this error after I added these lines to my gradle file:

buildTypes.each {
        it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY', MyOpenWeatherMapApiKey
    }

然后日志显示:

Could not find property 'MyOpenWeatherMapApiKey' on com.android.build.gradle.AppExtension_Decorated@c3b784

我在谷歌上搜索的解决方案无法解决我的问题.请告诉我我错在哪里?

The solutions on google that I searched cannot solve my problem. Please show me where I was wrong?

推荐答案

由于您使用的是 String，因此您必须使用以下语法:

Since you are using a String you have to use this syntax:

buildConfigField "String" , "OPEN_WEATHER_MAP_API_KEY" ,  "\"XXXXX-XXXXX-XXX\""

最后一个参数必须是字符串

The last parameter has to be a String

否则你可以使用这样的东西:

Otherwise you can use something like this:

resValue "string", "OPEN_WEATHER_MAP_API_KEY", "\"XXXXX-XXXXX-XXX\""

第一种情况会在您的 BuildConfig 文件中生成一个常量.
第二种情况生成可以使用 @string/OPEN_WEATHER_MAP_API_KEY 注释访问的字符串资源值.

The first case generates a constants iin your BuildConfig file.
The second case generates a string resource value that can be accessed using the @string/OPEN_WEATHER_MAP_API_KEY annotation.
