多次调用Gradle buildConfig

Question

我很难找到一种方法,使用Gradle为我的BuildConfig添加多行.看来,当我第二次调用buildConfig时,第一次消失.

我最初是从另一个地方添加这个buildConfig,但是如果我这样做的话,它能够创建一个最小的可重现测试:

buildTypes {
    debug {
        versionNameSuffix "-DEBUG"
        buildConfig "public static final int THING_ONE = 1;"
        buildConfig "public static final int THING_TWO = 2;"
    }
    release {
        zipAlign true
        buildConfig "public static final int THING_ONE = 3;"
        buildConfig "public static final int THING_TWO = 4;"
    }
}

然后当我尝试在代码中使用它时:

public class Thing {
    public static final int THING = com.example.BuildConfig.THING_ONE + com.example.BuildConfig.THING_TWO;
}

我会收到这个错误:

/Example/src/main/java/com/example/Thing.java:2: cannot find symbol
symbol  : variable THING_ONE
location: class com.example.BuildConfig
public static final int THING = com.example.BuildConfig.THING_ONE + com.example.BuildConfig.THING_TWO;

有没有办法为buildConlavor或buildType添加多个不同的行到buildConfig(使用多次调用buildConfig - 而不是多行字符串)？

正如@CommonsWare指出的那样,自Gradle 1.9(Android Studio 0.4.0)以来,你必须声明你的BuildConfig字段:

buildTypes {
    debug {
        versionNameSuffix "-DEBUG"
        buildConfigField "int", "THING_ONE", "1"
        buildConfigField "int", "THING_TWO", "2"
    }
}
