Details

I'm creating a simple library with multiple entries.
I have seen this: web-infra-dev/rsbuild#3702
But it still does not answer my question.
I want to import my components like this:

import { Button } from '@acme/ui/Inputs';

However, this doesn't work. I've managed to get it working using Vite and Rollup, but I want to migrate to rslib instead.
I'm likely making a mistake, but I can't find any documentation on how to resolve it.

My entries are set up as follows:

  source: {
    entry: {
      './Inputs': 'src/Inputs/index.ts',
      './Surfaces': 'src/Surfaces/index.ts',
    },
  },

I'm also receiving this warning:

duplicate entry: index, this may lead to the incorrect output, please rename the file
My exports configuration is:

  "exports": {
    "./Inputs": {
      "types": "./dist/Inputs/index.d.ts",
      "import": "./dist/index.js"
    },
    "./Surfaces": {
      "types": "./dist/Surfaces/index.d.ts",
      "import": "./dist/index.js"
    }
  },

I know the import is the same path because there is only one js file, I don't know why.
I've created a working example, which you can find here:

Ultimately, I want to be able to import components in this way:

import { Button } from '@acme/ui/Inputs';
import { Card } from '@acme/ui/Surfaces';

Reproduce Steps

1. run pnpm i to install all dependencies
2. run pnpm build to build all packages
   alternatively, run pnpm build --filter=@acme/ui to build only the ui package.

Try to set bundle: true, see https://lib.rsbuild.dev/config/lib/bundle#bundle-true

I changed it and made some updates to the bundle and it worked! I failed to understand what it meant in the documentation. Thank you for the help!
