I'm trying to switch from SVN to Mercurial. I've done converting, and now I have hg repository on https://bitbucket.org/CasualShammy/nameplateauras. I have set up webhook, and it works (returns http status 200), but curseforge packager doesn't want to create file. My steps:
I've already put in an issue for Mercurial repositories; it would seem that tags are currently processed as alpha files. Since your project is set up to only package on tags, this in effect ensures that nothing is ever packaged. As a workaround until this is fixed, you can turn on packaging for all commits and retroactively rename the file and set it to Release.
I know this isn't ideal, but it's either that or switch to Git for now.
