1. 确保您的AWS CDK Pipeline已与Bitbucket集成，并且已经设置了正确的触发器。
2. 您需要检查您的Bitbucket仓库是否配置了正确的Webhook，以触发管道。 以下是一个示例Bitbucket仓库配置的Python代码：

from aws_cdk import (
    core, 
    aws_codepipeline as codepipeline, 
    aws_codepipeline_actions as actions, 
    aws_codecommit as codecommit
)

class MyStack(core.Stack):

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

    # Your Bitbucket repository credentials
    bitbucket_conn = codecommit.CfnRepository.ConnectionArnProperty(
        arn="YOUR_BITBUCKET_CONNECTION_ARN_HERE"
    )

    # Creating an S3 Bucket
    bucket = s3.Bucket(
        self, "MyPipelineBucket",
        bucket_name="my-pipeline-bucket"
    )

    # Creating a CodeCommit Repository
    repository = codecommit.Repository(
        self, "MyRepository",
        repository_name="my-repository-name",
        connection_arn=bitbucket_conn
    )

    # Creating a CodePipeline Artifact Bucket
    artifact_bucket = s3.Bucket(
        self, "MyArtifactBucket",
        bucket_name="my-artifact-bucket"
    )

    #Creating an AWS CodePipeline using the CodeCommit Repository as input
    pipeline = codepipeline.Pipeline(
        self, "MyPipeline",
        pipeline_name="my-pipeline-name",
        artifact_bucket=artifact_bucket
    )

    #Creating a CodeCommit Source Action to retrieve the source code
    source_action = actions.CodeCommitSourceAction(
        action_name="CodeCommit",
        repository=repository,
        output=codepipeline.Artifact("SourceArtifact")
    )

    #Creating a build Action to compile and upload the Spark Jar to S3
    build_action = actions.CodeBuildAction(
        action_name="MyBuild",
        input=codepipeline.Artifact("SourceArtifact"),
        outputs=[codepipeline.Artifact("MyArtifact")],
        project=MyBuildProject
