在上一篇文章中, 我写了基于 svn 的将变动按 war 包目录提取的文章 https://www.jianshu.com/p/a2ec55f0da0a ,
这篇文章我做了一些优化, 使得脚本能处理 C R U D 等大部分情况, 不能处理的部分也会有合理的输出.
下面假设你的项目是标准的 eclipse java web 项目. 下面两个脚本配合, 可以将变动很方便的同步到测试环境部署,值得一提的是 rsync 非常非常快.

get_changes.sh

#!/bin/bash

# 这个脚本分析 svn diff -r commit1:commit2 --summarize 的输出, 找到两个 commit 间变动的文件,
# 按文件原有的目录结构 和 war 包的目录结构, 放到放在一个目录中.  
# 然后, 可以直接将该目录中的内容拖到 war 包中以实现快速准备 war 包; 或上传到测试服务器以实现部署

# 支持 新增, 修改; 删除不支持, 需手动删除.
