All, A short while ago Mojang released Minecraft 1.15.2 containing a couple minor bugfixes, and we have now also updated. SpigotMC Changes & Notes Update Checking: Reminder that the old update checker API was turned off. The new checker API is easier to use and faster, please see this thread. API: Please do not use the ItemStack class to hold Materials that are not items (Material.isItem() == false). This is nonsensical behaviour and will not be supported in a future version. Spigot: The Vanilla Server GUI has been re-added. If you do not wish to use it simply add the --nogui or nogui command line arguments. To better support this the default log4j2.xml has been synced back to the Vanilla version. If you are using a custom version you will need to update yours. CraftBukkit: As foreshadowed in the 1.14 thread, BuildTools will no longer build CraftBukkit by default. To compile CraftBukkit you must now use the --compile craftbukkit command line argument. In order to get 1.15.2, simply run the latest BuildTools. Code (Text): java -jar BuildTools.jar If you haven't used BuildTools to create a server jar yet, it is suggested you first read the 1.8 announcement and the additional BuildTools info thread. BungeeCord is also updated and can be found on Jenkins. Enjoy, ~md_5 A Note on NMS NMS is not supported API. It has never been and never will be. Whilst we recognise that some things possible with NMS are unlikely to be possible with the API, many things that NMS is used for are possible with the API, or would be possible with very trivial feature requests. Before using NMS for any reason you should carefully consider whether you really need to use it or not. Updates to NMS are a crucial aspect of being able to sustainably and reliably deliver new versions of Spigot and may occur without warning. As a developer using NMS you must ensure that your plugin gracefully handles unexpected situations. The only guarantee given about NMS is that CraftMagicNumbers.getMappingsVersion() will be changed if any mappings changes are made (which could be frequently).
