Got weird error while referencing from Codebuild source = buildspec.yml

❓ General Issue

The Question

I try to use codebuild with compose docker in docker and deploy to ECR hub.

While using buildSpec: BuildSpec.fromSourceFilename I encountered this error:

If the Project's source is NoSource, you need to provide a concrete buildSpec

xxxProject/node_modules/constructs/lib/construct.ts:407
        throw new Error(`Validation failed with the following errors:\n  ${errorList}`);
              ^
Error: Validation failed with the following errors:
  [Bob-Pipeline-dev] Stage 'Build' must have at least one action

If I use buildSpec: BuildSpec.fromObject, it works @@, no idea

Environment

• CDK CLI Version: 1.32.1
• OS: : OSX Catalina
• Language: Typescript

Sample code with buildspec.yml

File structure:

File: pipeline.ts

    const pipeline = new Pipeline(
      this,
      `Pipeline-${environment.ENV}`,
      {
        pipelineName: `pipeline-${environment.ENV}`,
      },
    )

    const sourceStage = pipeline.addStage({
      stageName: 'Source',
    })

    const buildStage = pipeline.addStage({
      stageName: 'Build',
      placement: {
        justAfter: sourceStage,
      },
    })

    const sourceOutput = new Artifact()

    const sourceAction = new GitHubSourceAction({
      actionName: `codebuild-action-${environment.ENV}`,
      owner: 'xxx,
      repo: 'xxx',
      oauthToken: cdk.SecretValue.secretsManager('tGitHubToken'),
      output: sourceOutput,
      branch: `${environment.branch}`,
      trigger: GitHubTrigger.WEBHOOK,
    })

    sourceStage.addAction(sourceAction)

const buildRole = new iam.Role(
      this,
      `IamRole-${environment.ENV}`,
      {
        assumedBy: new iam.ServicePrincipal('codebuild.amazonaws.com'),
      },
    )

    const codeBuild = new Project(
      this,
      `CodeBuildProject-${environment.ENV}`,
      {
        role: buildRole,
        environment: {
          buildImage: LinuxBuildImage.fromDockerRegistry('docker:dind')
        },
        buildSpec: BuildSpec.fromSourceFilename('./buidspec.yml')

    const buildAction = new CodeBuildAction({
      actionName: 'Build',
      input: sourceOutput,
      project: codeBuild,
    })

    buildStage.addAction(buildAction)
  }

Hey @ookangzheng ,

change Project to PipelineProject in your code, and everything will work again.

Thanks, Adam

Actually I realized that I split CDK and my code into 2 different separate Github Repositories. While I use codebuild.BuildSpec. fromSourceFilename('buildspec.yml'), I have to put buildspec.yml under my code repo.
