💻 Code

Running tsc -b on a project whose output has been deleted from disk does not regenerate that output. For example, if my project is a directory containing an empty test.ts file and a tsconfig.json like the following:

{
  "compilerOptions": {
    "incremental": true,
    "skipLibCheck": true,
    "tsBuildInfoFile": ".tsbuildinfo",
  }
}

Running tsc -b . the first time produces the file test.js. If I delete that file and run the command again, nothing happens. If I edit the source and run the command again, then the test.js file is generated as expected.

This applies to .d.ts and .map files as well. Additionally, if output directories are specified, like so:

{
  "compilerOptions": {
    // same as above, plus
    "outDir": "./lib",
    "declarationDir": "./types",
    "declaration": true,
    "declarationMap": true,
  }
}

Then the .d.ts file does not get regenerated (after being deleted from disk) even if I edit the source file.

🙁 Actual behavior

The output files do not get regenerated after being deleted from disk.

🙂 Expected behavior

I'd expect alll output files to be regenerated after being deleted from disk.
