java - 为什么我的WAR中没有包含JAR的Maven依赖关系？

我有2个Eclipse项目：（1）my-library，该项目构建my-library-1.0.jar；和（2）my-deployable，生成my-deployable-1.0.war。

my-library是的中列出的依赖pom.xml项my-deployable。
my-library在中引用了2个依赖项（2个Apache Commons JAR）pom.xml。

my-library 已注册到我的Nexus，并且可以检索它。

当我my-deployable-1.0.war使用Goals进行构建时clean compile package，my-library-1.0.jar包含在WEB-INF\lib文件夹中，但是预期的WAR中没有包含它的2个依赖项。我的印象是，我不需要在pom.xmlof中明确指定它们，my-deployable因为它们已在pom.xmlof中列出my-library。

为什么在构建WAR时不将my-libraryJAR的依赖项包含在my-deployableWAR中？

该pom.xml用于my-library读取：
