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

  buildTypes.each {
 it 
在我将这些行添加到我的gradle文件后出现此错误： .buildConfigField'String'，'OPEN_WEATHER_MAP_API_KEY'，MyOpenWeatherMapApiKey 
} 
  

然后日志显示：

 在com.android.build.gradle.AppExtension_Decorated@c3b784 
  

Google搜索到的解决方案无法解决我的问题。请告诉我我错了什么地方？


解决方案

由于您使用的是 String 您必须使用以下语法：



  buildConfigFieldString，OPEN_WEATHER_MAP_API_KEY，\XXXXX-XXXXX- XXX \
  

最后一个参数必须是字符串



否则，您可以使用以下内容：



  resValuestring，OPEN_WEATHER_MAP_API_KEY， \\XXXXX-XXXXX-XXX \
  

第一种情况会在您的 BuildConfig 文件。

第二种情况生成一个字符串资源值，可以使用 @ string / OPEN_WEATHER_MAP_API_KEY 注释。

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

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

then the log show:

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

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

解决方案

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

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

The last parameter has to be a String

Otherwise you can use something like this:

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

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.
