(codebuild): Add support new newly introduced event filter

[aseppala]

Describe the feature

A new feature has been recently introduced in AWS CodeBuild: https://aws.amazon.com/about-aws/whats-new/2024/04/aws-codebuild-managed-github-action-runners/. This feature enables to use AWS CodeBuild as GitHub Actions runner. However, using this feature requires to configure a new event filter which is currently not yet available in CDK.

Use Case

To be able to use 'aws-cdk-lib/aws-codebuild.Project' L2 Construct to define a runner for Github Action I need to be able to pass in FilterGroup.inEventOf(EventAction.WORKFLOW_JOB_QUEUED) but its not available so for now I'm force to use L1 Construct which requires setting up IAM roles etc which would be automatically created by the Project construct.

Proposed Solution

Introduce new value to aws-cdk-lib/aws-codebuild.EventAction enum: "WORKFLOW_JOB_QUEUED"

Hi @aseppala , thanks for requesting this feature.

Thanks @msambol for submitting the PR.

Until this issue is resolved, a working workaround is to use CDK escape hatch:

import { CfnProject, Project, Source, FilterGroup, EventAction } from 'aws-cdk-lib/aws-codebuild';

const project = new Project(this, 'Project', {
  projectName: props.projectName,
  source: Source.gitHub({
    ...
    webhookFilters: [
      FilterGroup.inEventOf(EventAction.PULL_REQUEST_CREATED),
    ],
  }),
})

const cfnProject = project.node.defaultChild as CfnProject
const triggers = cfnProject.triggers as CfnProject.ProjectTriggersProperty
const filterGroups = triggers.filterGroups as CfnProject.WebhookFilterProperty[][]
// remove wrong (PULL_REQUEST_CREATED) filter
filterGroups[0].pop()
// add correct (WORKFLOW_JOB_QUEUED) filter
filterGroups[0].push({
  type: 'EVENT',
  pattern: 'WORKFLOW_JOB_QUEUED',
})
