Velocity UI

最近在研究XWiki，它是支持Velocity的，所以就顺便调查了一把支持Velocity的编辑器。不过由于用惯了eclipse，自然是以eclipse的插件为主要调查方向了。
调查下来一共找到四个插件，其中一个叫veloedit，一个叫velocitywebedit,另外两个都叫veloeclipse，不过确实是两个不同的插件，一个在google code上，一个在sourceforge上。详细信息可以看参考资料。

功能简介

1. veloedit 1.0.2

总结

其实veloeclipse(sourceforge) 是基于veloedit进行二次开发而成的，多了很多功能。 从以上的功能列表对比来看，veloeclipse(sourceforge)无疑是很有优势的。不过我最近对google code挺有好感的，而且 veloeclipse(google code)也直接宣称自己支持Velocity 1.6，所以就直接选用这一个了。等以后有更大需求的话，再判断是否需要使用 veloeclipse(sourceforge)。

一点安装经验

这几个插件除velocitywebedit外，都是通过在线的update方式安装的，对于一些网速不怎么样或者无法访问网络的人来说，确实是很痛苦的。我这里以veloeclipse(google code)为例给个先下载再安装的手顺。从 http://veloeclipse.googlecode.com/svn/trunk/update/features/ 页面上，下载feature的最新版本(如com.googlecode.veloeclipse.ui_2.0.8.jar)，从 http://veloeclipse.googlecode.com/svn/trunk/update/plugins/ 页面上，下载plugin的最新版本(如com.googlecode.veloeclipse.ui_2.0.8.jar)。然后把两个jar分别 解压缩到同名文件夹com.googlecode.veloeclipse.ui_2.0.8下，再把这两个jar分别拷贝到eclipse的features和plugins目录下，重新启动eclipse就可以了。

我使用的是eclipse的galileo版本(3.5)，并且成功安装了veloeclipse(google code)。

如果对eclipse插件的安装方法感兴趣，可以参考我的另外一篇博客：eclipse中安装插件的几种方法
