I compile it from github,
I'm sure the code is up to date,but the author forget to edit the version in build.gradle,the plugin still have the latest version of functionality.
So It doesn't matter.
I only found a version of ItemsAdder from july 2023. But the plugin LoneLibs that Itemsadder requires, crashes on load every time. The developer for LoneLibs is trying to figure it out.
