Multiple signingConfigs for multiple variants

Question

How can I set different signing configs for different variants?

For instance, we currently have the buildtypes Debug/Beta/Release with 2 flavors, free and paid, resu

Answer 1

The https://stackoverflow.com/a/32810290/3961802 answer will not work.

    beta {
        productFlavors.free.signingConfig signingConfigs.freeBeta
        productFlavors.paid.signingConfig signingConfigs.paidBeta
    }
    release {
        productFlavors.free.signingConfig signingConfigs.freeRelease
        productFlavors.paid.signingConfig signingConfigs.paidRelease                
    }

In this case, the release build type will overwrite all flavors. So signing config for the freeBeta will be freeRelease.

At the moment, the only solution that I know is to sign all the build variants in a separate task.

signingConfigs {

    bananaDebug {}
    bananaBeta {}
    bananaRelease {}

    orangeDebug {}
    orangeBeta {}
    orangeRelease {}

    lemonDebug {}
    lemonBeta {}
    lemonRelease {}
}

productFlavors {

    banana {}

    orange {}

    lemon {}
}

buildTypes {

    debug {}

    beta {}

    release {}
}

applicationVariants.all {
    def flavorName = it.getFlavorName()
    def buildTypeName = it.buildType.name
    def buildVariantName = flavorName + buildTypeName.capitalize()
    def currentSigningConfig = signingConfigs.getByName(buildVariantName)

    it.mergedFlavor.signingConfig = currentSigningConfig
    // If you want to sign debug build
    buildTypes.debug.signingConfig currentSigningConfig
}

Answer 2

The answer linked is actually working fine. I got it to compile like this (with buildTools 1.3.1 and gradle-wrapper 2.7). The error you were having (Could not find property "free" on ProductFlavor container) is most certainly due to the fact that your build types are defined before the productFlavors in your build.gradle

This won't work

signingConfigs {
    freeBeta {}
    freeRelease {}
    paidBeta {}
    paidRelease {}
}    
buildTypes {
    debug {}
    beta {}
    release {}
}
productFlavors {
    free {}
    paid {}
}

This would work (simply swapping the definition order of the productFlavors and buildType)

signingConfigs {
    freeBeta {}
    freeRelease {}
    paidBeta {}
    paidRelease {}
}    
productFlavors {
    free {}
    paid {}
}    
buildTypes {
    debug {}
    beta {}
    release {}
}

Here's a full working example:

signingConfigs {
        freeBeta {
            keyAlias 'freeBeta'
            keyPassword 'test'
            storeFile file('C:/keystore.jks')
            storePassword 'test'
        }
        freeRelease {
            keyAlias 'freeRelease'
            keyPassword 'test'
            storeFile file('C:/keystore.jks')
            storePassword 'test'
        }
        paidBeta {
            keyAlias 'paidBeta'
            keyPassword 'test'
            storeFile file('C:/keystore.jks')
            storePassword 'test'
        }
        paidRelease {
            keyAlias 'paidRelease'
            keyPassword 'test'
            storeFile file('C:/keystore.jks')
            storePassword 'test'
        }
    }

    productFlavors {
        free {

        }
        paid {

        }
    }

    buildTypes {
        debug {

        }
        beta {
            productFlavors.free.signingConfig signingConfigs.freeBeta
            productFlavors.paid.signingConfig signingConfigs.paidBeta
        }
        release {
            productFlavors.free.signingConfig signingConfigs.freeRelease
            productFlavors.paid.signingConfig signingConfigs.paidRelease                
        }
    }
