Strange build errors, but only if src-tauri/target/release folder already exists

[Dylan190774]

Describe the bug

I added Tauri to an existing fresh Quasar project.
yarn tauri dev works great now.

However, yarn tauri build only succeeds the first time.
When I try it for the second time, it gives all kinds of weird errors, like :

src-tauri/target/release/build/app-cfcf12468c148780/out/tauri-codegen-assets/b55b3654b8ae09ecef9d94c6779bbb7dd3b5000505c861ffe50d5ca1ab489898.js:96:114 - error TS1137: Expression or comma expected.

It seems that if src-tauri/target/release/build already exists the errors occur. But if I remove this, the build takes very long again, so this is not really an option.
I added /src-tauri to .eslintignore, since I saw some errors that contained eslint , but this didn't solve the problem with the build.

Any idea what could cause this behaviour?

I did some more tests, and the problem seems definitely to be caused by eslint.

When I create a Quasar app that doesn't use eslinting, the errors do not occur.

However, of course I would like to be able to have eslint enabled.

Found a solution!
I had to add src-tauri to the exclude-section in tsconfig.json as well!
Now yarn tauri build works like a charm,too!

Hope this helps someone who uses Quasar, Vite, ESlint and Tauri in the same project :)

Thanks for the investigation, I will close the issue since it is related to your frontend configuration and not a bug in tauri.
