[pikax]

Describe the bug

When building with sourcemap:"hidden" some sourcemap will not be generated correctly and warning will be thrown:

vite-sourcemap-issue> yarn build
yarn run v1.22.10
warning package.json: No license field
$ vue-tsc --noEmit && vite build

The dist/assets/index.c52965d2.js.map is broken because the file only contains

{"version":3,"file":"index.c52965d2.js","sources":[],"sourcesContent":[],"names":[],"mappings":""}

Reproduction

• npm init @vitejs/app
• create vue-ts or vue
• go inside of the project folder
• run yarn
• go to vite.config.ts
• add :

  build: {
    rollupOptions: {
      output: {
        sourcemap: "hidden",
        // compact: true,
      },
    },
  },

• run yarn build

• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Provide a description in this issue that describes the bug.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to https://github.com/vuejs/vue-next instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.

This issue is caused by using the build.rollupOptions.output.sourcemap instead of vite build.soucemap

Vite should throw an warning mentioning the use of build.rollupOptions.output.sourcemap

Thanks to @antfu for figuring it out :)

build: {
        rollupOptions: {
            output: {
                sourcemap: "hidden"
            }
        }
    },

build: {
    sourceMap: "inline"  
}

I test above , but can't got the source-map in .vite

I don't think we need to throw a warning if rollupOptions is used to configure sourcemaps instead. I think it's already clear how sourcemaps can be configured following the docs.
