Garbage collector not deleting old fingerprinted assets

I have the following scenario:

  • Assets are generated (and minified) with my own build tool and put into the /assets/dist directory.
  • I have assetDir = "./assets/dist" in my config.toml
  • CSS, for example, is called in the template by requesting the file and fingerprint it.
  • When I build my site using hugo, it is correctly generated and put into the /public folder. Assets are fingerprinted correctly.
  • When I change assets and generate the site again, new fingerprinted assets are put into /public, but the old assets stay there.

1. run


2. run

app.4b7dd44[...]aa7b86ad8.css // old file
app.92e5d89[...]16b924298.css // new file

I assumed that this could be solved by using hugo --gc which is recommended for image generation anyway. I thought that the garbage collector would also clean old fingerprinted assets but they are still there.

Is this intended behaviour or am I doing something wrong?

Details about the setup

Source: Github

Assets are called this way:

{{ $appcss := resources.Get "app.css" | fingerprint }}
<link rel="stylesheet" href="{{ $appcss.Permalink | relURL }}">
$ hugo env
Hugo Static Site Generator v0.55.6/extended darwin/amd64 BuildDate: unknown
$ hugo --gc

                   | EN  | DE
  Pages            | 516 | 504
  Paginator pages  | 118 |  69
  Non-page files   |  64 |  38
  Static files     |  30 |  30
  Processed images | 126 |  76
  Aliases          | 205 | 229
  Sitemaps         |   2 |   1
  Cleaned          |   0 |   0

The --gc routine is cleaning file caches, but does nothing with /public. The suggested way is to delete /public before every build.

I use option --cleanDestinationDir . Works like a charm
