原来我的POM中groupId是org.tinygroup，artifactId是对应的工程名，如parser。
后出有一个处理上的原因，而且便于进行分隔，还可以避免与别人的冲突，想把所有的artifactId前面增加个“org.tinygroup.”前缀，比如parser就变成org.tinygroup.parser。但是这样一来，所有的依赖信息也全都对不上了，也就是要对工程的artifactId及依赖中的artifactId都进行修改才行。
由于工程数比较多，一个一个手工改总是麻烦的，因此就想着写程序进行处理。

呵呵，程序运行一会，马上搞定了。
当然，这个时候，可能感觉还是有点麻烦，OK，再换一种写法：

下面的xml格式化并输出到文件中，也可以写成：
|

|
formater.format(doc,fileObject.getOutputStream();
