本文介绍了一种在Eclipse 3.2中简化第三方库JAR文件升级的方法，通过使用Migrate JAR File功能，开发者可以轻松地用新版本的JAR替换旧版本，无需手动删除和添加JAR文件。

Replacing JARs on the Build Path  -- Eclipse 技巧

from:R.J. Lorimer 

在维护项目的一个普通的任务就是升级库文件,例如, 你在使用 commons-collections 在你的项目中,现在使用的是3.1,但是现在 3.2 发布了, 你想使用它. 所以你需要使用新的jar来替换旧的jar库文件.在eclipse3.2发布以前你需要做下面的几步来完成它.:

  1. Copy 新的jar文件到你的项目lib目录中
  2. 通过 操作[right-click project]->Properties...->Java Build Path->Libraries (tab)来删除类路径中的旧jar文件
  3. 添加新的jar文件到上面的路径中 
  4. 如果需要的话还要 重新命名类文件 or 更新文件引用

这样做是很郁闷的. 尤其是你使用一个使用很多第三方jar文件的工具时(如 hibernate,spring) 当你升级这些项目时,你要做很多上面的改动. 是不是很无趣呢.?

来看看Eclipse 3.2 给我们带来了什么吧.有一个新的特性叫 'Migrate JAR File',用来升级jar文件.要使用该功能,在要替换的jar文件上右击,进入 Build Path 子菜单选择 'Migrate JAR file':

你会看到下面的对话框:

如果你不走运也要根改jar文件名的话(保持原来的名字不变)你可以选中那个复选框..

然后点击finish, 你将看到你的jar文件已经升级了.

尽情享受吧!

重构，一步更换项目依赖jar

目标：两种操作重构依赖jar要用一个新版本更新构建路径上的 JAR 包，最常用的方法是： 进入项目的属性并将现存的 JAR 包从这个构建路径中删除。 手动地从其包夹中删除 JAR 包。 复制新的 JAR包，并将其重新命名以便反映其在所有构建脚本中被引用时所用的那个名字。 手动地向构建路径添加新的 JAR 包。然而，用 Migrate JAR File 重构，以上这些工作只需一步就可以完成。 演示例

JAR 文件就是 Java Archive File，顾名思意，它的应用是与 Java 息息相关的，是 Java 的一种文档格式，JAR 文件非常类似 ZIP 文件——准确的说，它就是 ZIP 文件，所以叫它文件包。JAR 文件与 ZIP 文件唯一的区别就是在 JAR 文件的内容中，包含了一个 META-INF/MANIFEST.MF 文件，这个文件是在生成 JAR 文件的时候自动创建的。
