Maven/Plexus ComponentLookupException-类路径噩梦？

有人知道下面的异常意味着什么，或者我应该如何开始调试或调查它吗？我觉得它相当神秘。我认为这意味着我在pom.xml中缺少了一个Maven依赖项，但我一生都无法弄清楚是什么

问候,

然后它列出了一大堆被排除的依赖项。我认为这些依赖性中的一些是必要的。我如何把它们包括在内？为什么他们被排除在外？这是什么逻辑

您是否尝试使用

-X

启动maven？谢谢您的建议。我根据主条目的输出添加了一些信息，我会在异常位置设置一个断点，看看到底缺少了什么元素。你能在没有Hudson的情况下复制吗？Hudson嵌入程序实际上是从fitnesse maven classpath调用的，而不是从Hudson调用的。我有一个断点，但当然，如果有东西丢失了，那么它就丢失了，这意味着我不知道应该在那里的是什么。唯一的线索是role=org.apache.maven.execution.mavenExecutionRequestPopulator我找到了一种完全不同的方法来实现我的目标，因为我没想到会很快就解决这个难题……你试过用
