发出远程存储库中存在的依赖项。

Question

在项目的pom.xml中，它具有要从远程存储库下载的依赖项。

<parent>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>plugin</artifactId>
    <version>1.567</version>
</parent>

<repositories>
    <repository>
        <id>repo.jenkins-ci.org</id>
        <url>http://repo.jenkins-ci.org/public/</url>
    </repository>
</repositories>

我理解的是Maven

1. 如果找不到本地存储库中的搜索
2. 如果找不到本地企业关系存储库中的搜索
3. 应该从远程存储库下载

当我执行命令mvn test时，它会显示如下所示的跟踪

在错误中，它显示它是从本地连接库下载的。

Could not find artifact org.jenkins-ci.plugins:plugin:pom:1.567 in nexus (http://localnexus/nexus/content/groups/group/) and 'parent.relativePath' points at no local POM 

有人能帮我解决这个问题吗。这与代理设置有关吗？

因为它不去远程存储库链接..

这类似于这个问题

如果从远程存储库获取父pom，则可以将父标记修改为

    <parent>
        <groupId>org.jenkins-ci.plugins</groupId>
        <artifactId>plugin</artifactId>
        <version>1.567</version>
        <relativePath></relativePath>
    </parent>

添加一个空的相对论性路径将解析存储库中的父POM。如果未指定relativePath，则默认为./pu.xml。

从医生那里，

签出中父pom.xml文件的相对路径。如果未指定，则默认为./头. not。Maven首先在文件系统的这个位置查找父POM，然后查找本地存储库，最后在远程回购中查找。relativePath允许您选择不同的位置，例如，当您的结构是扁平的，或者在没有中间父POM的情况下更深的位置。但是，组ID、工件ID和版本仍然是必需的，并且必须与给定位置的文件匹配，否则它将恢复到POM的存储库。此特性仅用于增强该项目的本地签出中的开发。将值设置为空字符串，以防要禁用该特性并始终解析存储库中的父POM。默认值是：./头.。
