xmake 自定义 task 没有办法转发参数么？

[githubnotebooks]

task("mybuild", function()
	set_category("action")
	set_menu({
		usage = "xmake mybuild",
		description = "mybuild ...",
		options = {
			{ nil, "args", "vs", nil, "..." },
		},
	})
	on_run(function()
		import("core.base.option")
		local args = option.get("args") or ""
		print(args)

		local args_str = table.concat(args, " ")
		print(args_str)
		os.exec("xmake build " .. args_str)
	end)
end)

在上述代码中，我想要将参数转发给 xmake build，如果是普通的构建目标，这是没问题的，但如果带有 -v，那么就不行了。

xmake mybuild -v t1  # 这里只将 t1 转发给 xmake build
xmake mybuild t1 -v  # 这里虽然将 t1 和 -v 都转发过去，但 xmake build t1 -v 是非法的，报错，必须是 xmake build -v t1 的形式

如果不能转发参数，那么当我的 task 内部调用 xmake build 的时候，我是不是得找到源代码，然后把 build 的 option 都拷贝到 mybuild 中？

task("build")
    set_category("main")
    on_run("main")
    set_menu {
                usage = "xmake [task] [options] [target]"
            ,   description = "Build targets if no given tasks."
            ,   shortname = 'b'
            ,   options =
                {
                    {nil, "version",    "k",  nil   , "Print the version number and exit."                            }
                ,   {'b', "build",      "k",  nil   , "Build target. This is default building mode and optional."     }
                ,   {'r', "rebuild",    "k",  nil   , "Rebuild the target."                                           }

参考下 watch 的实现

xmake/xmake/plugins/watch/xmake.lua

Line 47 in d7bdbc9

{'-', "arbitrary" , "vs" , nil , "Run an arbitrary command.",

xmake/xmake/plugins/watch/main.lua

Line 73 in d7bdbc9

local arbitrary = option.get("arbitrary")

哦我知道了，需要通过 -- 派发参数，必须是：

xmake mybuild -- -v arg1 arg2

此时 vs 类型的多值参数才能接收到 { "-v", "arg1", "arg2"} 这三个参数而不会把 -v 丢掉。
