Problem

Write a Jenkins pipeline to build and test a Java application built using Gradle.

Requirements

• Build will be set up to run as a multibranch pipeline covering both main branch and pull requests
• The following stages are required:
  • build
  • unit test
  • integration tests
• Integration tests should run on main branch only (not on PRs)
• Integration tests should time out after 30 minutes
• Credentials are required by all stages. Credentials id is credentials (secret text) and should be added as a flag to the gradle command (see below)
• Notifications should be sent to the builds slack channel when a build has failed, has test failures or is now fixed
• Option to send notification to a different slack channel
• How would we refactor into a shared pipeline?
• How would this pipeline handle custom post success behaviour?

Supplementary info

• Shared-library folder would normally be in a different repo. Assume this library is implicitely loaded
• Suitable k8s base agent can be used with a label of gradle
• To run gradle, the command line is: ./gradlew some_command --no-daemon -Pcredential=credentialValue
• Gradle commands
  • build - build
  • unit test - test
  • integration test - it
• slack notifications sent as slackSend message: message, color: colour, channel: slackChannel
