最近接项目要求，要在svn主干上创建分支，用分支来进行程序的bug修改，而主干上进行新功能的开发。分支上的bug修改完，发布后，可以合并到主干上。项目程序可以在主干和分支之间进行切换，来实现主干和分支的同时维护。
1.创建分支
创建分支实际上就是将程序copy一份到指定的分支目录，如下图示：
在项目名称上点击右键，弹出菜单，选择“Team”，再选择“Branch/Tag”，弹出下面的页面：
上图中的“Copy to URL”填写创建新分支的路径地址，后面会将程序copy到该目录下，形成新的分支。点击“Next”:
选择当前最新的版本，点击“Next”
如果勾选了上图下面的switch working copy to new branch/tag，eclipse的程序项目会自动切换到分支下。这里我们不选择，待会自己切换。
这样就创建了一个1.0的分支
2.合并
可以从主干合并到分支，也可以从分支合并到主干，根据需要可以选择合适的选项，如下图：
上图中的选项：
1) 从主干合并到分支
2) 从分支合并到主干
3) 将主干上的修改合并到分支
4) 合并2个分支到主干
5) 从主干到分支，手工指定不需要合并的修改
6) 从主干到分支，手工指定要合并的修改
上图显示没有任何修改，所以不用进行合并。
3.切换
在项目名称上点击右键，选择“Team” –> “switch to another Branch/Tag/Revision”。
选择需要切换的目的地址，点击ok即可。
这样，在项目里就可以在主干和若干分支间进行任意切换，来实现对不同版本/分支的程序进行修改提交操作。
合并需要用到一个插件，如图：

If you just want to install/update CollabNet Desktop, it is recommended to use the installation steps as discussed earlier in this page.
图文：eclipse中SVN分支合并到主干
============================================================================
在项目开发中，需要添加一些新的功能，但是又不想影响到其他开发人员的项目进度，所以决定使用SVN分支进行开发，分支开发完毕后再合并到主干。本文介绍如何在eclipse中合并分支到主干。
1. 要想将分支合并到主干，首先需要切换到主干。
在项目上面点右键，选择Team – 切换，URL地址为主干的访问路径。
2. 在项目上面点右键，选择合并，选中“merge two different trees”。
3. 在接下来的界面中选择如下：
From的路径填写主干的访问路径。在下面的版本选择中可以选择HEAD Revision（主干的最新版本），或者指定其他版本。
To的路径为分支的访问路径。可以在版本选择中选择HEAD Revision（分支的最新版本），或者指定其他版本。
点击Finish后会进行合并操作。
4. 解决冲突，提交到主干。
合并完成后会将分支和主干的文件进行合并。如果在分支和主干中同时修改了一个文件，这时可能会出现冲突，需要手动更新这个文件来解决冲突。当所有的冲突解决后，需要将修改提交到主干中，这样分支合并就完成了。分支可以继续保留在SVN中，如果不需要也可以删除。
