maven 将项目打成jar包

添加此plugin到项目的pom.xml

</archive>

<descriptorRef>

</configuration>
</plugin>
</plugins>
</build></project>

注意修改mainClass为main的入口类文件

<mainClass>fuck.notGood.JobRun</mainClass>

添加这个assmbly插件便可以打jar包了。在eclipse中，右键项目Run as->maven build 在Goals中输入assembly:assembly，点击run就可以了

执行成功后会在target文件夹下多出一个以-jar-with-dependencies结尾的JAR包. 这个JAR包就包含了项目所依赖的所有JAR的CLASS.
