如何将签名配置添加到 Multi-FlavorDimensions (ProductFlavors)？

Question

例如，我有一个 gradle 构建，如下所示：

signingConfigs {
        configFlavor1 {
        keyAlias 'alias1'
        keyPassword 'password1'
        storeFile file('location1')
        storePassword 'password1'
        v1SigningEnabled true
        v2SigningEnabled true
    }

    configFlavor2 {
        keyAlias 'alias2'
        keyPassword 'password2'
        storeFile file('location2')
        storePassword 'password2'
        v1SigningEnabled true
        v2SigningEnabled true
    }

    configFlavor3 {
        keyAlias 'alias3'
        keyPassword 'password3'
        storeFile file('location3')
        storePassword 'password3'
        v1SigningEnabled true
        v2SigningEnabled true
    }
}

flavorDimensions "dimen1", "dimen2"
productFlavors {
    flavor1 {
        dimension "dimen1"
    }
    flavor2 {
        dimension "dimen1"
    }
    testing {
        dimension "dimen2"
    }
    dev {
        dimension "dimen2"
    }
    prod {
        dimension "dimen2"
    }
}

现在我想使用特定于该风味维度组合的签名配置..例如..我想签名：

flavor1Prod with configFlavor1
flavor2Prod with configFlavor2
flavor1Dev with configFlavor3
etc...

我尝试过这样的事情

applicationVariants.all { variant ->
    def mergedFlavor = variant.mergedFlavor
    switch (variant.flavorName) {
        case "flavor1Prod":
            mergedFlavor.signingConfig = signingConfigs.configFlavor1
            break
        case "flavor2Prod":
            mergedFlavor.signingConfig = signingConfigs.configFlavor2
            break
        ... soo on...
    }
}

但每当我尝试运行时，它仍然尝试生成未签名的 apk。

有人可以帮我吗？
