Hi, any change I can build the package locally myself?

Your issue does not contain a valid output of the /version command and will now be closed and ignored.
Please create a new issue, follow the template and include a valid /version output.

Quoting my answer from Discord:

SilkSpawners requires the CraftBukkit jar files as dependencies for compilation of the version specific code (known as NMS, too) - due to the DMCA of CraftBukkit from 2014 (https://github.com/github/dmca/blob/master/2014/2014-09-05-CraftBukkit.md) one is no longer allowed to distribute those binaries (that's why you need to run BuildTools all the time and not just download the newest spigot.jar)

Because of the DMCA the artifacts are hosted in a private repo of my Artifactory server and only my Jenkins has access to it.
You'll need to run BuildTools for each version of Minecraft - this will populate your local Maven repository, too. That might be enough to build, otherwise, if the artifacts are present, you can remove the https://repo.dustplanet.de/artifactory/private repository entry from the pom(s)

But yes, it's a shame that it's so difficult to compile SilkSpawners yourself. I'll keep this as a reminder to add some instructions to the readme file.

Thank you!

Btw the README has been updated in #240
