有谁知道以下异常是什么意思，或者我应该如何开始调试或调查它？我觉得它相当神秘。我认为这意味着我的 pom.xml 中缺少一个 Maven 依赖项，但我一辈子都无法弄清楚是什么。
问候，

当我使用 -X 运行 Maven 时，会在异常之前稍稍获取一些额外信息，大致如下：
Created new class realm plugin>eg.example:artifact:1.0.0-SNAPSHOT
Importing foreign packages into class realm plugin>eg.example:artifact:1.0.0-SNAPSHOT
Imported: < maven.api
Populating class realm plugin>eg.example:artifact:1.0.0-SNAPSHOT
然后它列出了一大堆依赖项，例如：
Included: bouncycastle:bcprov-jdk15:jar:135
Included: mx4j:mx4j-tools:jar:3.0.1
Included: org.mortbay.jetty:servlet-api-2.5:jar:6.1.9
Included: net.jcip:jcip-annotations:jar:1.0
然后它列出了一大堆被排除的依赖项。我认为需要这些依赖项中的一些。我如何让它们包括在内？为什么他们被排除在外？这里发生了什么逻辑？
