Create repo in stack A and ref it to codepipeline in stack B throws 'cyclic reference'

See original GitHub issue

❓ General Issue

The Question

Stack A has a CodeCommit repo. I want the CodePipeline in Stack B to use this repo. This throws Adding this dependency (cdk-repo -> cdk-pipe/CodePipeline/Resource.Ref) would create a cyclic reference.

I just had a very similar problem #5657 where I manually needed to hard code the artifact bucket. However, this time the resource mentioned in the error is hardcoded. So I am unsure if this me not understanding how this is supposed to work or if this is unexpected behavior.


Here is a repo with an example of what I try to do.

#!/usr/bin/env python3

from aws_cdk import core

from cdk_repopipe.cdk_repo_stack import RepoStack
from cdk_repopipe.cdk_pipe_stack import PipelineStack

app = core.App()
repo_stack = RepoStack(app, "cdk-repo")
pipe_stack = PipelineStack(app, "cdk-pipe", repo_stack.repo)


from aws_cdk import (
    aws_codecommit as codecommit

class RepoStack(core.Stack):

    def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)

        # The code that defines your stack goes here
        self.repo = codecommit.Repository(self, "my-repo", repository_name="test-repo")

from aws_cdk import (
    aws_codecommit as codecommit,
    aws_codebuild as codebuild,
    aws_codepipeline as codepipeline,
    aws_autoscaling as autoscaling,
    aws_codepipeline_actions as codepipeline_actions,
    aws_codedeploy as codedeploy,
    aws_ec2 as ec2,
    aws_s3 as s3

class PipelineStack(core.Stack):

    def __init__(self, scope: core.Construct, id: str, repo: codecommit.Repository, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)

        # Pipeline
        artifactBucket = s3.Bucket(self, 'PipelineBucket',

        pipeline = codepipeline.Pipeline(self, "CodePipeline",
            artifact_bucket=s3.Bucket.from_bucket_attributes(self, 'ImportedBucket',
        # Source
        source_output = codepipeline.Artifact()
        source_action = codepipeline_actions.CodeCommitSourceAction(
        pipeline.add_stage(stage_name="Source", actions=[source_action])

        # Deploy
        deploy_application = codedeploy.ServerApplication(self, "CodeDeployApplication", 

        deployment_group = codedeploy.ServerDeploymentGroup(self, "DeploymentGroup",
        deploy_action = codepipeline_actions.CodeDeployServerDeployAction(
        pipeline.add_stage(stage_name="Deploy", actions=[ deploy_action ])

@skinny85 I’m also encountering the same issue. Is there any workaround for this behavior until a proper fix is implemented?

Is this a duplicate of #3087?
