You need to correct the importing of Moonlight Lib

This one can not be finded in maven.May be the maven repo is different one?

There are 2 ways:

1. importing from curse.maven or other sources (if you get to the page of "file" of any version via curseforge, you can look under the "Curse Maven Snippet", that's the one you should use to import the Moonlight lib)
2. importing the mod from curseforge (downloading the mod and put it in "mod folders" so it will get imported)
