SVN实现增量打包
很多情况下,项目只是修改个别文件, 需要更新到生产环境, 往往大量的配置文件等信息 需要修改后再打成war包,这样风险很大,而如果每个文件逐个替换会出现把有做修改的文件一个个挑出来，如果有成千上百的文件这样会疯掉,以下方法可以让你得到解救!
利用SVN版本号比较差异实现, 利用"svn diff -r m:n" 对版本m和版本n比较差异,得到版本之间修改的文件集合,将此集合循环解析并且复制拷贝到指定目录
因工作中的项目用到maven聚合,所以会有两个项目,FreePatchUtil中的路径可修改为自己svn对应本地路径
一 创建一个新项目 然后新建三个类
- OpenCommpant : 打开一个新窗口执行类FreePatchUtil
- FreePatchUtil : SVN构建,版本比较,文件拷贝
- CommandUtil : 调用服务器命令脚本
public class OpenCommpant {
public static void main(String[] args) {
try {
// String cmds = "cmd /k start java -cp c://command.jar com.plumnix.cmd.ReadWriteComponent";
Runtime.getRuntime().exec("cmd /k start java -cp " + System.getProperty("java.class.path") + " com.zhongwang.patch.FreePatchUtil");
} catch (Exception e) {
e.printStackTrace();

测试通过后,
二 导出可执行jar
1 右键项目 -> Export
2选择 Java -> JAR file -> Next
3选择导出项目 ,生成位置 -> Next
4 Next
6 生成后的jar 为可执行
