net.minecraftforge.fml.loading.moddiscovery.ModFile.findResource(Ljava/lang/String;)Ljava/nio/file/Path; is not implemented. It requires ModInfo stuff, which is complicated and not well understood. It will definitely take us some time to properly implement this feature.

If possible, you can have a look at the source code of the mod that you are trying to run. info.u_team.music_player.dependency.DependencyManager.findJarFilesInJar seems like a dependency check, remove this call and replace it with some dummy function may make it work.
