Unused import from external module prints massive indecipherable warning message

[benmccann]

Describe the bug

I've gotten this error message from vite, but don't know how to fix it. It's a pretty bizarre error message because it just tells me a bunch of files where the classes aren't used. But where are the offending classes actually imported?

"Sprite" and "CubeTexture" are imported from external module "three" but never used in

looks like this warning is coming from rollup:

• https://github.com/rollup/rollup/blob/c8082814fd1d518aadeb950fc7e8aa4e5e55bddb/src/utils/logs.ts#L1082
• https://github.com/rollup/rollup/blob/c8082814fd1d518aadeb950fc7e8aa4e5e55bddb/cli/run/batchWarnings.ts#L252

[benmccann]

Sigh. I guess I partially have myself to blame for this one: rollup/rollup#4194. Lol

To be fair, putting a huge list of files where you have to guess which one contains the error is slightly better than the old version, which told you nothing. And I was just using the information available where the real issue is the warning being generated without the relevant info

[bluwy]

I've seen this happen more often since a couple months ago, but I'm not sure it's related to Vite either. Perhaps it should be reported to Rollup instead? Maybe also worth testing downgrading Rollup versions.

[benmccann]

I was going to close this and file an issue with Rollup, but I can't reproduce it with Rollup alone: https://stackblitz.com/edit/rollup-repro-imroal

I'm guessing that there's something in Vite's TypeScript transformation that is triggering this or something along those lines
