使用 CodeBuildStep 的代码管道的 AWS CDK 合成器错误

Question

I am trying to implement an AWS Code-Pipeline using aws-cdk v2. Here is my code which does not have any errors but errors out while doing a cdk synth.

const pipeline = new CodePipeline(this, "MyPipeline", {
  pipelineName: "my-pipeline",
  synth: new CodeBuildStep("SynthStep", {
    input: CodePipelineSource.codeCommit(repo, "mainline"),
    buildEnvironment: {
      computeType: CodeBuild.ComputeType.MEDIUM,
      buildImage: CodeBuild.LinuxBuildImage.STANDARD_5_0,
    },
    partialBuildSpec: buildSpec,
    commands: [],
    role: codeBuildSynthRole,
  }),
  crossAccountKeys: true,
  selfMutation: true,
  dockerEnabledForSelfMutation: true,
});

I get an error - 'Only one build spec is allowed to specify artifacts.' What am i doing wrong?

You did not show your buildSpec but I suspect it includes artifacts. CodeBuildStep creates its own artifacts element. If you view the CDK source by control-clicking in your IDE on the partialBuildSpec , it says:

    /**
     * Additional configuration that can only be configured via BuildSpec
     *
     * You should not use this to specify output artifacts; those
     * should be supplied via the other properties of this class, otherwise
     * CDK Pipelines won't be able to inspect the artifacts.
     *
     * Set the `commands` to an empty array if you want to fully specify
     * the BuildSpec using this field.
