Is it possible to do "setup" initially and then "start_or_attach" at some later time ?

[blmhemu]

I was wondering if it is possible to do something like this:

-- .config/nvim/lua/nvim-jdtls.lua
require("jdtls").setup({
    cmd = cmd,
    dap = dap,
    other_opts = other_opts
})

-- .config/nvim/ftplugin/java.lua
require("jdtls").start_or_attach()

There is no "setup" for jdtls. You can collect all setting to config variable.

local function jdtls_on_attach()
    require("jdtls.setup").add_commands()
    require("jdtls").setup_dap()
    require("jdtls.dap").setup_dap_main_class_configs()
end
local config = {}
local home = os.getenv("HOME")
local workspace_folder = home .. "/.workspace/" .. vim.fn.fnamemodify(root_dir, ":p:h:t")
local bundles = {
    vim.fn.glob(
        home .. "/.local/bin/java-debug/com.microsoft.java.debug.plugin/target/com.microsoft.java.debug.plugin-*.jar"
    )
}
local settings =
{
        java = {
            contentProvider = {
                preferred = "fernflower"
            },
        },
}

config.init_options = {
    bundles = bundles,
}
config.settings = settings
config.on_attach = jdtls_on_attach
require("jdtls").start_or_attach(config)
