1.报错情况是：具体 报错：AWT is not properly configured on this server. Perhaps you need to run your container with “-Djava.awt.headless=true”? See also: https://jenkins.io/redirect/troubleshooting/java.awt.headless
java.awt.AWTError: Can’t connect to X11 window server using ‘localhost:10.0’ as the value of the DISPLAY variable.

2.解决：linux图形界面即可，在java启动时加选项java -Djava.awt.headless=true
在/usr/local/tomcat/bin/catalina.sh中开头添加如下参数
JAVA_OPTS=-Djava.awt.headless=true
