Best way to sign Jenkins Android apps with Gradle

Question

I am setting up Jenkins CI for our Android applications. I am completely new to Gradle and try to integrate it with Jenkins. I installed the Gradle plugin that runs assembleReleasein my applications.

Every possible application built with this CI must use the same keystore that will be signed.

What I've done:

• Create a Gradle script to store the alias / password and key store location:

  android {
      signingConfigs {
          release {
              storeFile file('/absolute/path/to/keystore')
              storePassword 'XXX'
              keyAlias 'XXX'
              keyPassword 'XXX'
          }
      }
  
      buildTypes {
          release {
              signingConfig signingConfigs.release
          }
      }
  }
  

• Then, in every project that is, the build.gradle file contains:

  if (new File('/path/to/the/build/file/above').exists()) {
      apply from : '/path/to/the/build/file/above'
  }
  
  buildTypes {
      release {
          **Project-specific config**
      }
  }
