Can someone let me know how does mvn dependency:analyze work ? An output of mvn dependency:analyze in one of my project shows

有人可以告诉我以下内容吗-

Can some one let me know the following -

• 使用的未声明的依赖项表示什么?这是否意味着这不是在 pom.xml dependencies 中声明而是在代码中使用并通过一些传递依赖项包含在内?
• 未使用的声明依赖项是否只检查pom.xml中声明的dependencies，还是也检查传递依赖项?

• What does Used undeclared dependencies found denote? Does it mean that this is not declared in pom.xml dependencies but getting used in code and is included via some transitive dependencies?
• Does Unused declared dependencies found check only for the dependencies declared in pom.xml or it checks transitive dependencies as well?

找到的使用的未声明依赖项表示什么?这是否意味着这不是在 pom.xml 依赖项中声明而是在代码中使用并通过一些传递依赖项包含在内?

What does Used undeclared dependencies found denote? Does it mean that this is not declared in pom.xml dependencies but getting used in code and is included via some transitive dependencies?

没错！

找到的未使用声明的依赖项仅检查 pom.xml 中声明的依赖项还是也检查传递依赖项?

Does Unused declared dependencies found check only for the dependencies declared in pom.xml or it checks transitive dependencies as well?

声明的依赖项是在您的 POM 中声明的依赖项.因此，该插件在其检查中不包含传递依赖项.

Declared dependencies are the dependencies that are declared in your POM. So the plugin does not include transitive dependencies in its check.

请注意，该插件默认进行字节码分析，这对于仅与常量或注释一起使用的依赖项存在问题.在某些情况下，这可能会导致错误报告.有关详细信息，请参阅常见问题解答.

Note, that the plugin does a byte-code analysis by default, which is problematic with dependencies that are only used with constants or annotations. This can lead to false reports in some situations. See the FAQ for details.
