Docker内部版本上的不可解析父POM

Non-resolvable parent POM on Docker Build(Docker内部版本上的不可解析父POM)

问题描述

我正在尝试从我的DockerFile构建Docker镜像，但不断收到错误消息，如找不到父pom.xml在docker文件中执行maven命令并构建项目。 我四处看了看，您看到人们所做的是将pom.xml添加到子项pom.xml引用父pom.xml y尝试向子项添加relativePath>.. /pom.xml/relativePath>，但仍然不起作用。

我不确定使用什么命令或如何使构建工作，谢谢您的帮助。

推荐答案

Maven是一种支持声明性方式管理项目依赖项的工具。它通过标准化项目共享JAR和POM文件(构件)的方式来实现这一点，并使用Maven坐标声明项目依赖项(groupID、artifactID和版本)，然后在名为Maven Central的JAR和POM文件的大型公共Maven存储库中进行查找。

为了将您的JAR/POM文件(例如您的核心)作为maven构件进行管理，您需要将您的构件部署到Maven Central(任何人都可以访问的公共存储库)或私有存储库中的某个位置(或者甚至在Internet上，并且可能使用身份验证)。对于私有存储库，您需要包括You私有存储库，这样您的maven执行不仅可以在Maven Central中查找构件，还可以在您的私有存储库中查找构件。您可以通过将以下内容添加到您的settings.xml文件中来实现此目的：

<!-- 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>
        <repository>
          <id>nexus-thirdparty</id>
          <name>nexus-thirdparty</name>
          <url>http://hostname_or_ip_address/content/repositories/thirdparty</url>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>nexus-plugin-release</id>
          <name>nexus-plugin-release</name>
          <url>http://hostname_or_ip_address/content/repositories/releases/</url>
        </pluginRepository>
        <pluginRepository>
          <id>nexus-plugin-third-party</id>
          <name>nexus-plugin-third-party</name>
          <url>http://hostname_or_ip_address/content/repositories/thirdparty/</url>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
...

我注意到您的子pom.xml文件引用了一个自定义父模块。您需要确保您的父模块位于maven存储库(Nexus/ArtiFactory)中，并且您提供了一个settings.xml文件，其中包含Docker容器能够提取父POM的存储库设置。
