所以我有这个 shell 脚本，可以将我的 AS3 类编译为 SWF 格式。

今天我想在元数据列表的“日期”参数中添加一个精美的时间戳。我正在尝试使用编译器选项-raw-metadata，但每次我尝试编译它都会给我这个错误：

Adobe Flex Compiler (mxmlc)
Version 4.6.0 build 23201
Copyright (c) 2004-2011 Adobe Systems, Inc. All rights reserved.

command line: Error: default arguments may not be interspersed with other options

Use 'mxmlc -help' for information about using the command line.

你们知道为什么会发生这种情况吗？我在做傻事吗？如果我不使用-raw-metadata但单独设置每个参数，它工作正常。

这是我的构建过程（Makefile）：
