How to configure an AWS CodeBuild buildspec to use a dynamic ReportGroup created by CloudFormation

AWS have recently (20/12/19) released support for shared CodeBuild Report Groups in CloudFormation

I'd like to use a ReportGroup in my CloudFormation, but can't see how I'm supposed to configure CodeBuild to use it.

It looks like reporting configuration is done in the buildspec. I can see an example of a hardcoded reference to a report group in this example buildspec snippet:

reports:
  arn:aws:codebuild:your-region:your-aws-account-id:report-group/report-group-name-1: #surefire junit reports
    files:
      - '**/*'
    base-directory: 'surefire/target/surefire-reports'
    discard-paths: false

Obviously, if I'm creating my ReportGroup via CloudFormation, I don't know the ARN to put into the buildspec.

So, my question is how can I inject a dynamically created report group ARN into the buildspec? Or is there a different/better way of configuring CodeBuild to use a ReportGroup created by CloudFormation?

If it is all being created by CloudFormation then you could add the buildspec.yaml creation to the template and add the ARN via the intrinsic function Fn::Sub or !Sub

  CodeBuildProject:
    Type: "AWS::CodeBuild::Project"
    Properties:
      Source:
        BuildSpec: !Sub |
          version: 0.2
          env:
            variables:
              key: "value"
              key: "value"
          phases:
            install:
              runtime-versions:
                runtime: version
              commands:
                - command
            pre_build:
              commands:
                - command
            build:
              commands:
                - command
            post_build:
              commands:
                - command
          reports:
            arn:aws:codebuild:${AWS::Region}:${AWS::AccontID}:report-group/${ReportGroupName}:
              files:
                - location
              base-directory: location
              discard-paths: yes
              file-format: JunitXml | CucumberJson

Take note of the !Sub after BuildSpec.

Where ReportGroupName is equal to the name property value given in AWS::CodeBuild::ReportGroup
