如何避免；重叠类“；maven构建中的警告？

我有一个模块，它依赖于其他两个项目，但我在使用构建项目时得到了这个模块

虽然没有出现错误，但我收到了很多关于重叠同一类的警告：

[WARNING] commons-logging-1.2.jar, jcl-over-slf4j-1.7.12.jar define 6 overlappping classes:

如何避免这些警告？

使用，并使用

mvn clean dependency:tree
# or (mvn 3)
mvn clean org.apache.maven.plugins:maven-dependency-plugin:3.0.1:tree

清洁

对于避免旧
目标
内容的任何副作用非常重要

然后，根据您使用的插件，您可以添加排除规则，如中所示，以避免出现这些错误消息

如中所示，
依赖关系树的2.5.1版本不与Maven 3.x.x一起运行。

使用全名
org.apache.maven.plugins:maven dependency plugin:3.0.1:tree
将强制使用maven dependency plugin的3.0.1版本。
您的问题是什么？[信息]---maven dependency plugin:2.5.1:tree（默认cli）@用户会话使用者---[警告]错误注入：org.apache.maven.shared.dependency.graph.internal.Maven3DependencyGraphBuilder java.lang.NoClassDefFoundError:org/sonatype/aether/graph/dependencyNode您使用的是什么版本的maven？apache maven 3.3.9如图所示，依赖关系树的2.5.1版本不与maven 3.x.x一起运行。尝试使用
mvn clean org.apache.maven.plugins:maven dependency plugin:3.0.1:tree
，以强制使用maven dependency plugin的3.0.1版本。@AnujVishwakarma很棒。我对答案进行了编辑，以便更好地说明依赖项全名的用法：树目标。
