各種mvn clean, update項目都不好使，最主要的是前兩天還正常使用，突然就好不使了
根據錯誤提示，首先找到該項目的目錄：
進行命令：
mvn dependency:tree 查看項目依賴樹：
根據項目中的提示
Found Banned Dependency: commons-logging:commons-logging:jar:1.2
查找到
是在這個包下 org.jxls:jxls-poi:jar:1.0.11
或者根據命令查找： mvn dependency:tree -Dverbose -Dincludes=“xxx”
找到以後，在項目中去除該包，再重新mvn clean install
