今天在使用mvn denpendecy:tree查看maven依賴樹的時候失敗了，錯誤日誌如下：
[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.
中文含義：當僅通過插件前綴而不是groupId和artifactId從命令行調用插件時，可能會發生這種情況。
例如，mvn help:effective-pom可以作爲mvn org.apache.maven.plugins:maven-help-plugin的縮寫。
鑑於僅使用前綴的情況下會發生這種錯誤，那麼便採用全命令臨時解決了依賴樹的查看問題：
mvn org.apache.maven.plugins:maven-dependency-plugin:tree
事後對比mvn denpendecy:tree發現dependency拼寫錯誤
正確的命令：mvn dependency:tree
