今天在使用mvn denpendecy:tree查看maven依赖树的时候失败了，错误日志如下：
[ERROR] No plugin found for prefix 'denpendecy' in the current project and in the plugin groups [org.sonarsource.scanner.maven, org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\wuxiaoyuan\.m2\repository), central (ht

This can happen when invoking a plugin from the command line by giving only its prefix instead of its group and artifact id, e.g. in mvn help:effective-pom the token help is the plugin prefix and can serve as an abbreviation of org.apache.maven.plugins:maven-help-plugin.
中文含义：当仅通过插件前缀而不是groupId和artifactId从命令行调用插件时，可能会发生这种情况。
例如，mvn help:effective-pom可以作为mvn org.apache.maven.plugins:maven-help-plugin的缩写。
鉴于仅使用前缀的情况下会发生这种错误，那么便采用全命令临时解决了依赖树的查看问题：
mvn org.apache.maven.plugins:maven-dependency-plugin:tree
事后对比mvn denpendecy:tree发现dependency拼写错误
正确的命令：mvn dependency:tree
