cdk.Include : Not updating the external template changes.

[Black742]

cdk.Include constructor doesn't incorporating the changes in the external template to the CDK app.

Steps to replicate:

1. Create a test.yaml file with some sample resource.

    const SPEC_FILE_LOCATION = "test.yaml";
   let template: any =yaml.safeLoad(fs.readFileSync(path.join(__dirname, SPEC_FILE_LOCATION), 'utf8'));
   
   new cdk.Include(this, 'IncludeConfigTemplate', { template });
   
   

2. Deploy the app.
3. Update the text.yaml file with the below output code.

Outputs:
  TestOutput:
    Description: 'test'
    Value: 'test'
    Export:
      Name: 'testcdkupdate'

4. Build and run the deploy command. The stacks not getting updated and outputs the below msg.
   Stack was already up-to-date, it has ARN arn:aws:cloudformation:ap-southeast-2:***********:stack/HelloCdkStack/3ff234e0-e930-11e8-b0c7-027753bcaabc

Note: While running cdk diff, the changes are showing the as difference.

$ cdk diff
[+] Added TestOutput: {"Description":"test","Value":"test","Export":{"Name":"testcdkupdate"}}

Version used is 0.14.0

Additional to the description, have tried to use the cdk.output constructor to update the template. However, the template is not getting updated.

new cdk.Output(this, "test", {
      description: 'test',
      value: "test"
  });

Have a stack already and trying to make update on the stack. However the stack is not getting updated. Could you please help me on this?

It's a known issue that just adding a cdk.Output will not cause a deployment to execute. This is CloudFormation behavior that we haven't adapted for yet. There should be a couple of open issues on this already, for example #778 #186

[rix0rrr]

If you add a resource to your stack (a typical example is a WaitConditionHandle) your stack will deploy.

Thanks for the response. Have added additional resource and the stack getting updated.
