Multiple S3SourceActions returns "already a Construct with name" error

When adding more than one S3SourceAction to a pipeline I get a duplicate Construct name error.

jsii.errors.JSIIError: There is already a Construct with name ‘joetestintegrationpipelinePipeline5832AB7ESourceEventRule’ in Bucket [Bucket]

Reproduction Steps

from aws_cdk import (
    aws_codepipeline_actions as actions,
    aws_codepipeline as pipe,
    aws_s3 as s3,
    core
)

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

        pipeline = pipe.Pipeline(self, "Pipeline")
        pipe_bucket = s3.Bucket(self, "Bucket", versioned=True)
        action1 = actions.S3SourceAction(
            bucket=pipe_bucket,
            bucket_key='test1',
            output=pipe.Artifact(),
            action_name='test1',
            trigger=actions.S3Trigger.EVENTS
        )
        action2 = actions.S3SourceAction(
            bucket=pipe_bucket,
            bucket_key='test2',
            output=pipe.Artifact(),
            action_name='test2',
            trigger=actions.S3Trigger.EVENTS
        )

        source_stage = pipeline.add_stage(
            stage_name='Source',
            actions=[action1, action2])

Thanks for opening the issue @joekiller . You’re correct; a quick way to unblock yourself is to change one the of those actions.S3Trigger.EVENTS to actions.S3Trigger.POLL.

I’ll see what I can do here - the edge case here is that you’re using the same bucket twice in the pipeline, with different paths, which we didn’t anticipate.

NP @joekiller , glad it’s working now!
