1.新建maven工程
注意勾选
随便填一下
建好之后工程目录如下
新建测试类与工具类，主类很简单
工具类也很简单，就是初始化了日志
maven依赖包也只有一个log4j的jar
<dependencies>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
</dependencies>
如图
打可执行jar的时候肯定想把对应的依赖包log4j也打进去，不然不能正常运行哈
#####################重点是pom.xml的配置##############################

</project>
之后右键工程maven -> update project
再然后在工程上右键run as -> maven install
基本到这里就完成了，现在看看target目录
这块的jar就是我们需要的包含依赖jar包的可执行jar文件
