Eclipse 修改注释的 date time 日期时间格式，即${date}变量格式
找到eclipse安装目录下面的plugins目录，搜索 org.eclipse.text ，找到一个jar包，
例如我找到的jar包为：org.eclipse.text_3.5.300.v20130515-1451.jar
然后打开它，找到这个类： org.eclipse.jface.text.templates.GlobalTemplateVariables
我们重写这个类就行了。（可反编译，也可以找到源码，源码下载地址为：http://git.eclipse.org/c/platform/eclipse.platform.text.git，下载zip包） PS：如果嫌下载源码包麻烦，我这里贴出这个文件的源码，可以直接用（注：这个类很简单，无多少依赖，所有版本通用，无需担心jar包的版本问题）

自行拿去修改就行了。改一下Date Time Year就行了，例如，我修改的结果如下：

我改成了使用
import java.text.SimpleDateFormat;
import java.util.Calendar;
并且从properties文件中读取format格式，可以借鉴。
我提供编译好的class文件供大家下载（下载下面的图片，把jpg后缀 改成rar后缀，然后打开），替换到原文件即可。
