vite build using old cached source file?

[glittle]

Describe the bug

I had an unterminated string constant in a Vue file.

As expected, the 'server.hmr.overlay' showed the error and the line that caused it...

[plugin:vite:eslint] C:\myproject\src\pages\LoginPage.vue
  59:11  error  Parsing error: Unterminated string constant. (49:11)

I fixed the error and saved the file.

The same error was displayed again.

In attempting to resolve this, I edited the file a number of times and stopped and started the vite process.

Two ways to resolve the issue:

• copy the file content to a new file with the same name, replacing the old file
• rename the file and update code to reference the renamed new file

Reproduction

Not possible.

The page in question is loaded with this line:

import LoginPage from "@/pages/LoginPage.vue";

The builder seems to be using a cached file... but only after the "Unterminated string constant" error.

The bot has marked this for deletion because a repo was not provided. As explained, it cannot be.

If there's no repro, there's no way for us to fix it. The behaviour described alone isn't enough to figure the source of the bug.

[glittle]

Yes, I understand. We can let this be closed. I've got a workaround for when it happens again. And if someone else encounters the same issue, maybe this report will be a another clue to help identify the cause.

If the build system doesn't do any caching, then maybe there was some glitch in the environment. If there is any sort of caching, maybe it should be reviewed to ensure that this can't happen.

Thanks, @bluwy, for carrying forward the conversation. As mentioned, I'm fine with letting this issue be closed.
