Maven不解決來自私人回購的間接依賴關係

Question

我有一個關於maven的問題。我只是用eclipse mars使用m2e，maven版本是3.3.3。它無法解決我的nexus私有存儲庫中的間接依賴關係。

例如，有3個項目：common-A，common-B，biz-X。

• common-A和common-B都在nexus private repo中部署爲jar。
• common-B取決於common-A。 biz-X取決於共同B。所以biz-X間接取決於普通的A.
• biz-X項目成功下載了common-B。

問題是，biz-X無法下載common-A.jar。

任何人都可以幫助我！謝謝！

UPDATE1：

我有一些進步，這裏是M2E的堆棧跟蹤：

看來，行家說，她無法理解的共同-B的POM文件。但是我發現有包括一個pom.xml在下載共B.jar，位置是：

/META-INF /行家/（一些包裝）/common-B/pom.xml

它實際上是我在項目common-B的根目錄中定義的pom。 但爲什麼maven不加載它？ 或者如果這個pom文件不是maven需要的？ 或者如果pom文件需要從私人回購下載？如果是這樣，我發現common-B-0.0.1-yyyyMMdd（可能是seq）.pom在正確的nexus repo目錄中的jar文件的相同位置，maven不會加載它？是否因爲我將這個工件部署爲SNAPSHOT類型？ 或者是否有一些我需要做的「mvn deploy」操作？

以上是線索。希望他們有用。

UPDATE2：

哦，我....我必須跟我開玩笑。我找到了原因。因爲我忘了部署一個root pom，所有常見的工件都會擴展它。現在問題解決了。感謝你們！

您需要兩個版本庫的URL，以及快照庫網址添加到pom.xml中（或）settings.xml中

請嘗試將兩個URL作爲鏈接指定：
