Gradle build failure after new 2021.3 build

My mod I've been working on was created in 1.16.5, and I had installed the APIs Reborn plugin to help with development. One of the plugins it came bundled with was GeckoLib, and it seems to have not properly transferred all its files after I reinstalled MCreator with the 2021.3 update to work with 1.17. This has caused an error that is preventing my gradle from being properly started up when I open my workspace. I was going to attempt a reinstallation of the plugin, but I'm worried that removing it will cause even more issues for my workspace files. I went ahead and copied the error I've been receiving (this is not the whole thing, as it's far too many lines long for me to put in this post)

The only things I changed were the 100 or so lines of all the file paths the software searched through and removing my name. Other than that, this is the exact text I keep getting as an error. If anyone understands what is going on here (my ooga booga monkey brain sure can't), I would appreciate some help.
