Request #16188 has been rejected by diabonas [1]: The upstream project is alive and appears to be generally useful, so a deletion does not seem to be warranted. The AUR package works fine after updating to the latest version 4.0.0 (https://github.com/GraphWalker/graphwalker- project/releases/download/4.0.0/graphwalker-cli-4.0.0.jar). If you don't use the package any more, you can disown it so that somebody else can take over maintenance.
