What you can try is to use https://repo.helpch.at/releases/ as the repository URL instead of the extendedclip one.

Also, make sure that when you try to build a jar, that you provide the -U flag to force maven to refresh dependencies, as it could cache the broken one.

What is your project configuration? Because this looks like a misconfiguration to me.
