I do not understand how the webpack-stats.json file ended up in the wrong location as it is configured to be outputted in the static directory where make is invoked, aka the root directory of swh-web (see configuration).

Could you share a way to reproduce the issue ?

Ways to reproduce:

1. Clone the repository.
2. Follow developer-setup guidelines.
3. Makefile.local was not running somehow, so I renamed that as Makefile itself and then executed make commands.

I invoked the make run-django-webpack-devserver command from my root directory named swh.
Here is the snapshot of the directory structure.

The file is being generated in the swh/static location instead of finding out the subdirectory of static located inside swh-web. It might be due to the same directory name (swh), however, it should not be the case. Ideally, it works after placing it within the static folder of swh-environment.

Ok, got it, you did not follow the developer setup guidelines correctly.

Based on what I see, you cloned the swh-web repository, renamed it to swh then cloned the swh-environment repository inside the swh-web one.
You should have:

1. clone the swh-environment repository
2. setup a swh virtualenv with project path targetting the swh-environment repository
3. clone the swh packages inside the swh-environment folder using the ./bin/update script

The source code of swh-web will then be located in swh-environment/swh-web, executing make run-django-webpack-devserver from it will then work as expected.
