如何告诉maven-dependency-plugin项目中使用了该工件？
这是我的多模块项目的结构：
/root
/api dependencies: slf4j
/foo dependencies: slf4j-log4j12, log4j
换句话说，模块 api 使用 slf4j 进行日志记录。它不知道日志记录设施的实现是什么。模块 foo 添加了 slf4j-log4j12 和 log4j 以实现日志记录。很简单。
现在我正在运行 maven-dependency-plugin:analyze-only ，这就是模块 foo 的含义：
[WARNING] Unused declared dependencies found:
[WARNING] org.slf4j:slf4j-log4j12:jar:1.6.1:compile
[WARNING] log4j:log4j:jar:1.2.16:compile
这意味着该插件不理解 foo 确实需要这些依赖项。我该如何解决这个问题？
This is a structure of my multi-module project:
/root
/api dependencies: slf4j
/foo dependencies: slf4j-log4j12, log4j
In other words, module api uses slf4j for logging purposes. It doesn't know what the implementation of logging facility will be. Module foo adds slf4j-log4j12 and log4j in order to implement the logging. Pretty simple.
Now I'm running maven-dependency-plugin:analyze-only and this is what it says for module foo:
[WARNING] Unused declared dependencies found:
[WARNING] org.slf4j:slf4j-log4j12:jar:1.6.1:compile
[WARNING] log4j:log4j:jar:1.2.16:compile
Meaning that the plugin doesn't understand that foo really needs these dependencies. How can I solve the problem?

如果您为这些依赖项提供运行时范围而不是编译范围，会发生什么情况？
如果您将它们定义为编译时依赖项，我认为依赖项插件会认为编译需要它们，但实际上并非如此。但运行时您只需要 slf4-log4j 和 log4j JAR 文件。
编辑：您可能需要设置
ignoreNonCompile选项：http://maven.apache.org/plugins/maven-dependency-plugin/analyze-mojo.html
What happens if you give those dependencies a
runtimescope instead ofcompile?If you've defined them as compile-time dependencies I think the dependency plugin will think they are needed for the compile when they're really not. But you only need the slf4-log4j and log4j JAR files at runtime.
Edit: You may need to set the
ignoreNonCompileoption:http://maven.apache.org/plugins/maven-dependency-plugin/analyze-mojo.html
您是否尝试过将
slf4j-log4j12和log4j的范围设置为运行时？请参阅 maven 依赖范围
Have you tried setting the scope of
slf4j-log4j12andlog4jto runtime?See maven dependency scope
