Maven不解决来自私人回购的间接依赖关系

Question

我有一个关于maven的问题。我只是用eclipse mars使用m2e，maven版本是3.3.3。它无法解决我的nexus私有存储库中的间接依赖关系。

例如，有3个项目：common-A，common-B，biz-X。

• common-A和common-B都在nexus private repo中部署为jar。
• common-B取决于common-A。 biz-X取决于共同B。所以biz-X间接取决于普通的A.
• biz-X项目成功下载了common-B。

问题是，biz-X无法下载common-A.jar。

任何人都可以帮助我！谢谢！

UPDATE1：

我有一些进步，这里是M2E的堆栈跟踪：

看来，行家说，她无法理解的共同-B的POM文件。但是我发现有包括一个pom.xml在下载共B.jar，位置是：

/META-INF /行家/（一些包装）/common-B/pom.xml

它实际上是我在项目common-B的根目录中定义的pom。 但为什么maven不加载它？ 或者如果这个pom文件不是maven需要的？ 或者如果pom文件需要从私人回购下载？如果是这样，我发现common-B-0.0.1-yyyyMMdd（可能是seq）.pom在正确的nexus repo目录中的jar文件的相同位置，maven不会加载它？是否因为我将这个工件部署为SNAPSHOT类型？ 或者是否有一些我需要做的“mvn deploy”操作？

以上是线索。希望他们有用。

UPDATE2：

哦，我....我必须跟我开玩笑。我找到了原因。因为我忘了部署一个root pom，所有常见的工件都会扩展它。现在问题解决了。感谢你们！

您需要两个版本库的URL，以及快照库网址添加到pom.xml中（或）settings.xml中

请尝试将两个URL作为链接指定：
Adding Snapshot Repo to pom.xml
