本文介紹了Docker內部版本上的不可解析父POM的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！
問題描述
我正在嘗試從我的DockerFile構建Docker鏡像，但不斷收到錯誤消息，如找不到父pom.xml在docker文件中執行maven命令并構建項目。
我四處看了看，您看到人們所做的是將pom.xml添加到子項pom.xml引用父pom.xml y嘗試向子項添加relativePath>.. /pom.xml/relativePath>，但仍然不起作用。

我不確定使用什么命令或如何使構建工作，謝謝您的幫助。

Maven是一種支持聲明性方式管理項目依賴項的工具。它通過標準化項目共享JAR和POM文件(構件)的方式來實現這一點，并使用Maven坐標聲明項目依賴項(groupID、artifactID和版本)，然后在名為Maven Central的JAR和POM文件的大型公共Maven存儲庫中進行查找。
為了將您的JAR/POM文件(例如您的核心)作為maven構件進行管理，您需要將您的構件部署到Maven Central(任何人都可以訪問的公共存儲庫)或私有存儲庫中的某個位置(或者甚至在Internet上，并且可能使用身份驗證)。對于私有存儲庫，您需要包括You私有存儲庫，這樣您的maven執行不僅可以在Maven Central中查找構件，還可以在您的私有存儲庫中查找構件。您可以通過將以下內容添加到您的settings.xml文件中來實現此目的：
<!-- Authentication here -->
<servers>
<server>
<id>nexus</id>
<username>some_username</username>
<password>some_passowrd</password>
</server>
</servers>
...
<profiles>
<profile>
<id>nexus</id>
<!--Override the repository (and pluginRepository) "central" from the
Maven Super POM -->
<repositories>
<repository>
<id>nexus-release</id>
<name>nexus-release</name>
<url>http://hostname_or_ip_address/content/repositories/releases</url>
</repository>

我注意到您的子pom.xml文件引用了一個自定義父模塊。您需要確保您的父模塊位于maven存儲庫(Nexus/ArtiFactory)中，并且您提供了一個settings.xml文件，其中包含Docker容器能夠提取父POM的存儲庫設置。
這篇關于Docker內部版本上的不可解析父POM的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，
