💻 Code

// tsconfig.json
{
  "compilerOptions": {
    "tsBuildInfoFile": "./.cache/tsconfig.tsbuildinfo"
  }
}

🙁 Actual behavior

Error: Option 'tsBuildInfoFile' cannot be specified without specifying option 'incremental' or 'composite' or if not running 'tsc -b'.

🙂 Expected behavior

No error if incremental or composite is not specified with tsBuildInfoFile.

According to the Typescript 5.6 announcement:

TypeScript now always emits a .tsbuildinfo file for any project in a --build invocation (even if --incremental/--composite is not specified)

Additional information about the issue

The issue goes away if tsconfig.json is renamed to anything else, e.g. tsconfig.app.json.

The build process with tsc --build ./tsconfig.json is successful even though VSCode shows an error in tsconfig.json.

The issue can't be reproduced in the TypeScript Playground because tsBuildInfoFile can't be configured there.
