各种mvn clean, update项目都不好使，最主要的是前两天还正常使用，突然就好不使了
根据错误提示，首先找到该项目的目录：
进行命令：
mvn dependency:tree 查看项目依赖树：
根据项目中的提示
Found Banned Dependency: commons-logging:commons-logging:jar:1.2
查找到
是在这个包下 org.jxls:jxls-poi:jar:1.0.11
或者根据命令查找： mvn dependency:tree -Dverbose -Dincludes=“xxx”
找到以后，在项目中去除该包，再重新mvn clean install
