手動確定了 /opt/jdk1.8.0_191/bin/java 和 /var/lib/jenkins/workspace/xinguan 都是正常存在的目錄，但還是報錯沒有文件或目錄

於是乎手動執行了一下上面提示的命令：

[root@harbor jdk1.8.0_191]# /opt/jdk1.8.0_191/bin/java -cp /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven35-agent-1.13.jar:/opt/maven-3.6/boot/plexus-classworlds-2.5.2.jar:/opt/maven-3.6/conf/logging jenkins.maven3.agent.Maven35Main /opt/maven-3.6 /var/cache/jenkins/war/WEB-INF/lib/remoting-3.33.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven35-interceptor-1.13.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven3-interceptor-commons-1.13.jar
-bash: /opt/jdk1.8.0_191/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

哦吼，問題出來了，缺少依賴包glibc.i686，安裝

yum install glibc.i686 -y
