https://github.com/elmcgill/springboot-nvim/blob/main/lua/springboot-nvim/init.lua#L3.

Here is a missmatch with the filename. I think it should be `require("create_spring_project") not "create_springboot_project".

https://github.com/elmcgill/springboot-nvim/blob/main/lua/create_spring_project.lua#L205.

Here is a spelling mistake.
im.api.nvim_create_user_command("SpringNewProject", spring_new_project, {}) should be prob vim.api.nvim_create_user_command("SpringNewProject", spring_new_project, {})
