Question

我试图在一个全新的系统中使用我的自定义Maven插件。它似乎无法解析自定义Maven插件使用的父POM。

我尝试过几件事，但我不知所措。

非常感谢任何见解。谢谢。

更新

这很奇怪....只有当我清理本地存储库（模拟一个干净的系统，如新的开发人员或集成系统）时，才会出现此错误。如果我再次立即运行'mvn -U install'命令（根本不更改命令），那么它会成功构建！

这尖叫'传递依赖'，但我怎么发现这种违规行为？

更新

我认为这是Maven中的一个错误。反应堆找不到父POM，即使它位于同一个项目中！你们都在想什么？

自定义插件POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>my.org</groupId>
        <artifactId>parent-java-with-foundation</artifactId>
        <version>11.1.1.8-SNAPSHOT</version>
        <relativePath></relativePath>
    </parent>

    <groupId>my.org.maven</groupId>
    <artifactId>maven-plugin</artifactId>
    <version>11.1.1.8-SNAPSHOT</version>

</project>

这可能有几个原因。如果父POM不是反应堆的一部分（=当前版本）而你删除了本地缓存，那么Maven必须在某处找到它。

如果您有公司范围的存储库，请确保从那里获得此版本。特别确保您可以下载SNAPSHOT版本（某些repos可以禁用该版本，另外您可以配置Maven永远不会从某些存储库下载快照）。

如果您没有公司范围的存储库，则需要先在父项目中运行mvn install。 Maven并不试图在硬盘上的任何地方找到丢失的部分。

自定义Maven插件在另一个干净项目中使用时不解析父POM
