What were you expecting to happen?

Launching a Gulp task doesn't produce any warning.

What actually happened?

Since Node.js v23, an ExperimentalWarning is triggered.

This is because the requireOrImport() function uses require() to check if the gulpfile is a CommonJS module... but now Node.js allows to use require() for loading ES modules. So the ERR_REQUIRE_ESM error is not triggered anymore.

See: https://nodejs.org/en/blog/release/v23.0.0

Please give us a sample of your gulpfile

This issue is not related to the content of the gulpfile.
But feel free to test this project: https://github.com/cedx/lcov.js

Terminal output / screenshots

(node:26792) ExperimentalWarning: CommonJS module [...]\gulp-cli\lib\shared\require-or-import.js is loading ES Module [...]\gulpfile.js using require().

Please provide the following information:

• OS & version [e.g. MacOS Catalina 10.15.4]: Windows 11

• npm version (run npm -v): 10.9.0

Additional information

The launched tasks still run fine (unless the gulpfile uses top-level await). There is no runtime error, just an ExperimentalWarning.
