I'm using the version of 1.7.2-10.12.2.1161 forge, however it couldn't run minecraft launcher. It said "errors exsists in required projects". If I proceed, it can't run net.minecraft.launchwrapper and shows "Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release".Launch. Is this because the version is too old?
