JS/CSS not compiling with multiple blocks in create-block when created in a symlinked directory.

[shoelaced]

Description

If using @wordpress/create-block to create a new plugin with multiple blocks within a directory that is a symlink, the JS/CSS does not compile if the commands are run from within the symlink, rather than from within the original target directory. After investigating, I found that this was because in @wordpress > scripts > utils > config.js on line 236, there is this:

if ( ! filepath.startsWith( srcDirectory ) ) {

If I cd into the plugin through the original directory path, the files compile fine, however if I cd into the plugin through the symlink path, then they don't. This appears to be because when I'm in the symlink directory, the filepath variable contains the symlink path, whereas the srcDirectory variable still contains the original directory (symlink target) path, thus the if comparison fails.

Please view the reproduction steps for further clarification.

Step-by-step reproduction instructions

Please note that the symlink command below is specific to Windows:

1. Create a directory plugins somewhere, and create a new @wordpress/create-block plugin inside it.
2. Create a symlink of the plugins directory in another location called plugins2.
   On Windows: mklink /d "C:\path\to\plugins2" "C:\path\to\plugins"
3. Move everything in the plugin's src folder into a sub-folder: src\block-a, and rename the block name to block-a appropriately in blocks.json and in all the other block files.
4. In your terminal, cd into the plugin directory through the symlink's path: cd C:\path\to\plugins2\plugin
5. Run npm run build.

You should then see this notice in the terminal:

Skipping "./index.js" listed in "C:/path/to/plugins2/plugin/src/block-a/block.json". File is located outside of the "src" directory.
No entry file discovered in the "src" directory.

And, in the build/block-a folder, there will only be the blocks.json file.

If, however, you cd into the original plugins directory and attempt the build again, it will succeed.

Thanks for the report.
I think this issue is exactly the same as #44937, so let's close this issue and focus the discussion on #44937.
