今天用buildConfigField设置编译时常量遇到了问题，访问不到BuildConfig类，import导包也找不到类，具体设置如下：

    defaultConfig {
        applicationId 'com.sample.abc'
        minSdk 28
        targetSdk 33
        versionCode getVerInt()//1
        versionName getVerName()//"1.0"
        
        

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

        buildConfigField "String", "Build_ENV", "\"abc\""
        buildConfigField "String", "Build_VEHICLE_TYPE", "\"type1\""
    }

原因是buildConfigField脚本写在了testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"脚本之后；

写在testInstrumentationRunner语句之前就可以解决了，代码如下：

    defaultConfig {
        applicationId 'com.sample.abc'
        minSdk 28
        targetSdk 33
        versionCode getVerInt()//1
        versionName getVerName()//"1.0"

        buildConfigField "String", "Build_ENV", "\"abc\""
        buildConfigField "String", "Build_VEHICLE_TYPE", "\"type1\""
        

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

        
    }
