My requirements were that anyone without the keystore should be able to build properly. This is the cleanest way I could find:

android {
    signingConfigs {
        release    //Filled in readSigningConfigIfAvailable()
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-xyz.txt'
            readSigningConfigIfAvailable()
        }
    }
}

private void readSigningConfigIfAvailable() {
    if (hasAllSigningProperties()) {
        android.signingConfigs.release.storeFile = file(keystore_path)
        android.signingConfigs.release.storePassword = keystore_password
        android.signingConfigs.release.keyAlias = key_alias
        android.signingConfigs.release.keyPassword = key_password
        android.buildTypes.release.signingConfig = android.signingConfigs.release
    } else {
        android.buildTypes.release.signingConfig = null
    }
}

private boolean hasAllSigningProperties() {
    (hasProperty('keystore_path')
    && hasProperty('keystore_password')
    && hasProperty('key_alias')
    && hasProperty('key_password'))
}
