How to config jenkinsfile's kubernetes gradle version ?

[Break4ever]

The following jenkinsfile is my part of example:

containers: [
containerTemplate(name: 'android-env', image: 'thyrlian/android-sdk:latest', ttyEnabled: true, command: 'cat', alwaysPullImage: false),
containerTemplate(name: 'docker', image: 'docker:19.03.1-dind', ttyEnabled: true, command: 'cat'),
containerTemplate(name: 'curl', image: 'byrnedo/alpine-curl:0.1.8', ttyEnabled: true, command: 'cat')
]

How to config gradle version and kotlin version for 'thyrlian/android-sdk:latest' image ? @thyrlian

Hi @Break4ever.

If I'm not mistaken, in the given example you use Kubernetes plugin, sorry that I know nothing about it. I understand that you would like to have specific versions of Gradle or Kotlin used in your Android build environment, that's not a problem, but not exactly the way you planned.

We don't provide Docker images with all versions of tools, for below reasons:

• According to Android's terms and conditions, one may not redistribute the SDK or any part of the SDK. This is mentioned in the README. Thus, we're supposed to provide only a skeleton of an environment.
• There are a bunch of other supporting tools, such as Java, Kotlin, Gradle, a developer/team can use any combination of different versions of those tools based on the requirement, we can't build them all to satisfy everyone.

Having that said, it's just a matter that you can't pull any existing images, but no one can stop you from customizing and building your own image. It's actually fairly simple. From the README, the building command is:

docker build --build-arg JDK_VERSION=<jdk_version> --build-arg GRADLE_VERSION=<gradle_version> --build-arg KOTLIN_VERSION=<kotlin_version> --build-arg ANDROID_SDK_VERSION=<android_sdk_version> -t android-sdk android-sdk

I've checked Kubernetes plugin's guide, and it seems there is only an option of pulling an image, but not building. However, with the Docker Pipeline, you can build on your own:

docker.build("my-image:${env.BUILD_ID}", "--build-arg GRADLE_VERSION=<gradle_version> --build-arg KOTLIN_VERSION=<kotlin_version> -f Dockerfile .")

Hope this helps.
