Production build assumes existence of `inc/` directory within project root

[jaymcp]

What happened?

When running a build, Build Tools assumes the existence of an inc/ directory in the project root. If the directory doesn't exist, a raw error is thrown by Node.js as Build Tools attempts to write to the file inc/asset-settings.php.

Ideally, Build Tools would attempt create the directory (if it doesn't exist); alternatively, a more user-friendly error message could be thrown.

The command I am running to reproduce this is

build-tools build --production --once

My directory structure looks like the following:

project/
  - dist/
  - src/
  - package.json
  - webpack.config.js
  - yarn.lock

Which environments are you experiencing the issue on?

CLI (macOS, Windows, etc)

@jonmcp Which version of Build Tools are you running here?

[jaymcp]

I was actually running on #hotfix/handle-overwritten-externals, but experience the same output on v1.2.2

[ampersarnie]

@jonmcp I've done some testing and the problem isn't the missing asset-settings.php, it's a missing inc/ directory. If that directory exists, then the asset-settings.php file is created as expected.

I've found the following file and directory structures work as expected:

✅ Working:

inc/
src/
 - entrypoints/
   - frontend.js

✅ Working:

inc/
 - asset_settings.php
src/
 - entrypoints/
   - frontend.js

❌ Failing:

src/
 - entrypoints/
   - frontend.js

Tested by using the example-site and removing the inc directories in test-client-plugin and test-plugin. The following command run:

cd example-site
node ../src/cli.js build --once test-client-plugin,test-plugin

Ah; thanks for that, and apologies for not attempting that during my testing prior to creating this issue.
I can confirm that adding an empty inc directory resolves the error.
Would you like me to update the issue title and description for clarity?

[ampersarnie]

@jonmcp Yeah that would be great thank you.
