Description

Fixes #38739.

Addressed the issue raised by @loxK in #38584 (comment).

This prevents passing custom entry point in our workflow. Exemple:

import config from "../../config.js"

/** Gulp and utils **/
import gulp from 'gulp'

const {src, dest} = gulp

import named from 'vinyl-named'

/** Webpack **/
import webpack from 'webpack-stream'
import webpackConfig from "@wordpress/scripts/config/webpack.config.js"
webpackConfig.entry = null

/**
 * Scripts
 */
export const process_js = () => src( config.paths.scripts_sources.src )
        .pipe( named() )
        .pipe( webpack( webpackConfig ) )
        .pipe( dest( config.paths.scripts_sources.dst ) )

Returns the error:

No entry files discovered in the "src" folder.

Please revert:

if ( ! entryFile ) {
	log(
		chalk.bold.red( 'No entry files discovered in the "src" folder.' )
	);
	exit( 1 );
}
	

to

if ( ! entryFile ) {
	return {};
}

I followed the recommendation and added an early return when there is no src directory. In case when the src directory exists then the script still shows the warning but it returns the defaul value for entry which is {}.

I also included a missed CHANGELOG entry for #38584.

Testing Instructions

Run:

npx wp-create-block my-block --no-wp-scripts
cd my-block
../node_modules/.bin/wp-scripts build

Try removing a script file referenced in the block.json and run the build again:

../node_modules/.bin/wp-scripts build

You should see a warning and the build should run but it will only copy a block.json file:

If you rename the src directory then the build should still run but will finish without any files processed:

Prettier didn't like the changes and I had to fix that in the trunk with c034da1. I was too fast with merging ... 🙈
