有谁知道以下异常意味着什么，或者我应该如何开始调试或调查它？我觉得它很神秘。我认为这意味着我在我的pom.xml中缺少Maven依赖，但我不能为我的生活找到解决方法。
此致

当我使用-X运行Maven时，在异常之前稍微获取一些额外的信息，如下所示：
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
然后它列出了包含的一大堆依赖项，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部分。我如何将它们包含在内？他们为什么被排除？这里有什么逻辑？
