Customizing a CI/CD pipeline for code transformation

Amazon Q for code transformation performs some of its capabilities using static analysis, and this requires your compile and test scope dependencies to be provided in addition to your project source code. Code transformation for GitLab uses a GitLab CI/CD job to provide access to those dependencies.

Before you can invoke code transformation for your project, you need the following:

  • At least one GitLab Runner.

  • CI/CD feature must be enabled on the project.

  • A .gitlab-ci.yml committed on the project’s default branch.

To customize a CI/CD pipeline for code transformation

  1. If your project doesn't already have a GitLab CI/CD pipeline, create one using the Maven.gitlab-ci.yml template provided by GitLab. For more information, see Create a project pipeline..

  2. Update the .gitlab-ci.yml file with the following job:

    q-code-transformation:
  stage: build
  script:
    - 'mvn $MAVEN_CLI_OPTS test-compile'
    - 'mvn $MAVEN_CLI_OPTS dependency:copy-dependencies -DoutputDirectory=dependencies -Dmdep.useRepositoryLayout=true -Dmdep.copyPom=true -Dmdep.addParentPoms=true'
  artifacts:
    name: q-code-transformation-dependencies
    paths:
      - dependencies/*
  rules:
    - if: $CI_COMMIT_REF_NAME =~ /^q\/transform-/ && $CI_PIPELINE_SOURCE == 'push'
      when: always

    • The first mvn invocation validates that your project compiles before Amazon Q code transformation attempts to process it. The goal may be one of test-compile, test, integration-test, or verify.

    • The second mvn invocation copies project dependencies to a staging directory to include them as job artifacts.

    • The artifacts section uploads the copied dependencies so they can be accessed by Amazon Q code transformation.

    • The rules section configures this job to only run on branch names that start with q/transform-* when a new commit is pushed. That isn't the case when a merge request is opened.
