The best way for finding conflict in your pom file is using:在 pom 文件中查找冲突的最佳方法是使用：
mvn dependency:tree > somefile.txt
or或者
mvn dependency:tree -DoutputFile=myFile.dot -DoutputType=dot
then you can search for a specific library and you will be able to find out if there is any duplicate library with a different version in your dependency.然后您可以搜索特定的库，您将能够找出您的依赖项中是否有任何具有不同版本的重复库。 Also, The verbose mode tells the tree plugin to show dependencies that are duplicates of another or in conflict with another's version.此外， verbose模式告诉树插件显示与另一个重复或与另一个版本冲突的依赖项。
mvn dependency:tree -Dverbose
