To Reproduce

buffalo new buffet --db-type sqlite3
buffalo dev

Executing buffalo dev a second time will complete successfully, though it's not ideal.

(I added <details> tag in your original post to make it short and can see the details when it is required)

Thanks for the report.

I think the issue is a side effect of the behavior of Webpack and the workaround for embed. The missing file keep is a kind of placeholder to make embed runs without error even if the directory is initially empty, but I found the file was removed after Webpack runs. (As far as I remember, this behavior is somewhat different than before.) The sequence was maybe,

1. buffalo dev executed Webpack and go build
2. go build detected file list for assets (including keep)
3. Webpack removes all existing files including keep
4. go build tried to read the file but it was just removed by webpack

As described above, it seems like Webpack removes all pre-existing files when it dumps its new files into the assets directory. The next time, the file keep is not an issue anymore, but this issue could happen again because the other asset files could be in the same situation.

I will check it in more detail.

Found the root cause:

https://github.com/gobuffalo/cli/blob/0e3b085227c7aa963dee240f249ee136f62dd836/internal/genny/assets/webpack/templates/webpack.config.js.tmpl#L93-L97

was introduced to fix the other issue by gobuffalo/cli#71 and it made Webpack removes all existing files under the target destination directory by default. (https://webpack.js.org/guides/output-management/#cleaning-up-the-dist-folder)

Since this issue happens randomly, just ignoring the error could be one option for now, or removing the config clean: true from the webpack.config.js could be another option if the issue happens frequently.

FYI, buffalo build command has an option --clean-assets for cleaning the asset directory when it builds a binary.

I will keep this issue open and will revisit again to find a better solution.
