Signing product flavors with gradle

Question

I am tyring to migrate my projects to gradle. One of my projects has multiple product flavors and each one of them has to be signed with a different signingConfig in its release version. So this is what I tried so far:

buildscript {     ... }  apply plugin: 'android'  android {     compileSdkVersion 17     buildToolsVersion '17'      signingConfigs {         flavor1 {             storeFile file("keystore")             storePassword "secret"             keyAlias "aliasForFlavor1"             keyPassword "secretFlavor1"         }          flavor2 {             storeFile file("keystore")             storePassword "secret"             keyAlias "aliasForFlavor2"             keyPassword "secretFlavor2"         }     }      productFlavors {         flavor1 {             signingConfig signingConfigs.flavor1         }          flavor1 {             signingConfig signingConfigs.flavor2         }     } }  dependencies {     ... } 

When I run gradle build I get a groovy.lang.MissingFieldException and the following error message:

No such field: signingConfigs for class: com.android.build.gradle.internal.dsl.GroupableProductFlavorFactory 

So I assume the productFlavors.* part of the Gradle script is not the right place to put code signing configurations.

You can declare signing config for each flavor in buildType. Here is my gradle file for release signing flavors with different keystores.

android {   signingConfigs {     configFirst {         keyAlias 'alias'         keyPassword 'password'         storeFile file('first.keystore')         storePassword 'password'     }      configSecond {         keyAlias 'alias'         keyPassword 'password'         storeFile file('second.keystore')         storePassword 'password'     }   }    compileSdkVersion 23   buildToolsVersion "23.0.2"   defaultConfig {         minSdkVersion 14         targetSdkVersion 23   }    productFlavors{     flavor1 {         applicationId "com.test.firstapp"     }      flavor2 {         applicationId "com.test.secondapp"     }   }    buildTypes {     release {         productFlavors.flavor1.signingConfig signingConfigs.configFirst         productFlavors.flavor2.signingConfig signingConfigs.configSecond                     minifyEnabled true         proguardFiles getDefaultProguardFile('proguard-android.txt'),                 'proguard-rules.pro'      }   } } 

buildTypes block should be placed after productFlavors block, I mean order is important.
