Hello, i tried to update my plugin to 1.17. I have a NMS Class for each version (1.8-1.16), on that class i have a setTag method which should set a NBT Tag. While trying to update the plugin to 1.17 i'm stuck on the following issue. The affected Code of the older versions looks like that: Code (Java): net.minecraft.server.v1_16_R3.ItemStack nmsStack = CraftItemStack.asNMSCopy(itemStack); NBTTagCompound compound = nmsStack.getTag(); On a update i normaly just replace the version (also on the import). But on 1.17 my IDE (Intellj) sugessted me to use the following code Code (Java): net.minecraft.world.item.ItemStack nmsStack = CraftItemStack.asNMSCopy(itemStack); NBTTagCompound compound = nmsStack.getTag(); But while compiling i get two errors: - cannot find symbol (symbol: class NBTTagCompound) - bad class file: /home/false/git/Builder-s-Wand/../all-spigot-nms/all-spigot-nms.jar(/net/minecraft/nbt/NBTTagCompound.class) [ERROR] class file has wrong version 60.0, should be 57.0 I'm using maven and the projekt All Spigot NMS to get all versions. I also tried to ignore the suggestion of the IDE and just replace the version number as usual, but there is no "v1_17_R" folder which also means i cant find the class ItemStack for 1.17_R1.. Maybe you could help me with that... THANKS!
