Code.fromAsset("...") is not updating lambda-functions

Description

When I create a lambda-function within a cdk-stack based on Code.fromAsset("dist", { exclude: ["**", "!lambda-already-bundled-with-webpack.js"] }), then the lambda-function, when deployed for the first time, works fine. But when a code-update to the lambda-function is made, a re-deploy of the same cdk-stack is not updating the code of the deployed lambda-function. The lambda-function still has the old code from the first deployment. A cdk diff also says that no changes were detected…

I just tried your example and it worked fine for me.

The CDK app I used -

import { Function, Code, Runtime } from '@aws-cdk/aws-lambda';
import { App, Stack } from '@aws-cdk/core';

const app = new App();
const stack = new Stack(app, 'mystack-lambda');

new Function(stack, 'myfn', {
  runtime: Runtime.NODEJS_12_X,
  handler: 'index.handler',
  code: Code.fromAsset('resources', {
    exclude: [ '**', '!a.js']
  })
})

The resources/ folder looks like this -

⇒  tree resources
resources
├── a.js
├── b.js
└── fs
    └── c.js

1 directory, 3 files

and the asset folder looks like this -

⇒  tree cdk.out/asset.612208983ad862413ed9c910ace722035cd862a55d2b8d203a2e04c7538ea257
cdk.out/asset.612208983ad862413ed9c910ace722035cd862a55d2b8d203a2e04c7538ea257
└── a.js

0 directories, 1 file

I believe this matches what was intended with the exclude option.
