前言

一般情况下，多module的项目数量过少，可能不需要使用到这个功能，但是当项目过多就很有必要，例如有20个module 编译到最后一个报错了，那重新构建的话 就会从第一个项目再来一遍，是不是很烦躁。

实践

要从特定的某个module(项目)开始重新编译，可以使用Maven的-rf标志（resume from），指定从特定项目重新开始编译。

# xx 标识从哪个项目开始编译
mvn -U clean package -Dmaven.test.skip=true  -rf :xx

示例 现在项目有个报错

可以看到 编译到第四个项目 datax-core 报错了 那我下次想从datax-core开始编译 就可以使用如下命令

# 这样就会从datax-core 项目开始编译 而不是从第一个项目开始编译 大大减少编译时间
mvn -U clean package assembly:assembly -Dmaven.test.skip=true  -rf :datax-core

good day ！！！
