[aws-cdk] gitpod.io Vanilla Environment cdk synth error - Unable to compile TypeScript

[AndyEfaa]

I'm in the process of contributing to the cdk code base, I setup a new cdk gitpod.io environment.
To verify everything is working as expected, I created a small very basic cdk app in gitpod.io.
The operation cdk synth fails with an error that is unrelated to my stack (Lambda and CustomResource error even though they are not being used.)

The cdk app works fine on my local machine.

Reproduction Steps

Go to https://gitpod.io/#https://github.com/aws/aws-cdk and start up a new environment.

Create a new cdk app and link local dev environment:

~/aws-cdk/$ cd ..
# create a new CDK application
~/$ mkdir my-example-cdk-app
~/$ cd my-example-cdk-app
~/my-example-cdk-app/$ npx cdk init --language typescript
# link the locally-built CDK version into your application for testing
~/my-example-cdk-app/$ ../link-all.sh
# you can verify it worked by running a CDK command
~/my-example-cdk-app/$ npx cdk --version
0.0.0 (build ab12cd34)

Build a small test app stack (the code was copy & pasted from the CDK docu), such as:

import * as cdk from '@aws-cdk/core';
import * as codepipeline from '@aws-cdk/aws-codepipeline';
import * as codepipeline_actions from '@aws-cdk/aws-codepipeline-actions';
import * as codebuild from '@aws-cdk/aws-codebuild';
import * as codecommit from '@aws-cdk/aws-codecommit';


export class MyExampleCdkAppStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // The code that defines your stack goes here
    const repository = new codecommit.Repository(this, 'MyRepository', {
    repositoryName: 'MyRepository',
    });
    const project = new codebuild.PipelineProject(this, 'MyProject');

    const sourceOutput = new codepipeline.Artifact();
    const sourceAction = new codepipeline_actions.CodeCommitSourceAction({
    actionName: 'CodeCommit',
    repository,
    output: sourceOutput,
    });
    const buildAction = new codepipeline_actions.CodeBuildAction({
    actionName: 'CodeBuild',
    project,
    input: sourceOutput,
    outputs: [new codepipeline.Artifact()], // optional
    });

    new codepipeline.Pipeline(this, 'MyPipeline', {
    stages: [
        {
        stageName: 'Source',
        actions: [sourceAction],
        },
        {
        stageName: 'Build',
        actions: [buildAction],
        },
    ],
    });

  }
}

Run CDK:

npx cdk synth

What did you expect to happen?

I expected a successful cdk synth operation.
The cdk app works fine on my local machine.

What actually happened?

I received the following error dispite not using any CustomResource and Lambda:

gitpod /workspace/aws-cdk/my-example-cdk-app $ npx cdk synth
npx: installed 8 in 1.815s

Hey @AndyEfaa ,

thanks for opening the issue. I just tried to reproduce your problem, and I was not able to (for me, the application synthesizes correctly). See the following snapshot: https://gitpod.io/#snapshot/afc113d0-833d-40ee-95bf-8d805fa0384a

Thanks,
Adam

Hi Adam,
i can confirm that your gitpod environment does not show the behaviour I'm experiencing.

I created a snapshot of my gitpod environment that is having the issue:
https://gitpod.io/#snapshot/4ba4a160-4ef4-4653-8c3f-cae20db8bc05

There is a sample cdk app under /workspace/test1

Thank you
