今天想清理一下Linux主机上的一些无用内容，结果发现好多java -cp启动的东西，命令是这样的

    1. java -cp /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven33-agent-1.13.jar:/opt/maven/boot/plexus-classworlds-2.5.2.jar:/opt/maven/conf/logging jenkins.maven3.agent.Maven33Main /opt/maven /var/cache/jenkins/war/WEB-INF/lib/remoting-4.2.1.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven33-interceptor-1.13.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven3-interceptor-commons-1.13.jar

    于是乎对java -cp产生了好奇

    1. 分解上面命令

      1. 指定主类

        1. java -cp /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven33-agent-1.13.jar:/opt/maven/boot/plexus-classworlds-2.5.2.jar:/opt/maven/conf/logging jenkins.maven3.agent.Maven33Main

      2. 指定主类入参(用空格间隔)

        1. /opt/maven /var/cache/jenkins/war/WEB-INF/lib/remoting-4.2.1.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven33-interceptor-1.13.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven3-interceptor-commons-1.13.jar

    2. java -cp

    -cp就是指定引入的一些需要的jar文件路径，最后指定一个主类

    1. java -cp jar路径1:jar路径2:jar路径3:... 主类 参数1 参数2 ...
