java - Maven 不解决依赖关系 - 的 POM for ... 丢失

问题描述

我有两个包——一个叫 jhdf，另一个是 src。我的主要位于 src。但是我的 POM.XML 在我运行后一直给我错误mvn compile：The POM for jhdf is missing, no dependency information available

我很确定这就是我得到第二个错误的原因：Failed to execute goal on project test: Could not resolve dependencies for project edu.cs.test:0.3-SNAPSHOT: Could not find artifact edu.cs.jhdf:jhdf:jar:0.1-SNAPSHOT in osgeo (http://download.osgeo.org/webdav/geotools/)

这是我的 POM.XML 文件（如果您注意到我确实列出了我的 jhdf 依赖项）：

我究竟做错了什么？我试图查看类似的问题，例如 [this] one - 但没有运气。任何事情都会有所帮助，谢谢！

解决方案

看起来您已经删除了https://repo1.maven.org/maven2/io/jhdf/jhdf/0.3.0的 maven 中央存储库中提供的依赖项“io.jhdf:jhdf:0.3.0” /

并将其替换为 osgeo 存储库中不可用的“edu.ucr.cs.jhdf:jhdf:jar:0.1-SNAPSHOT”，因此您正在寻找的工件尚未在那里发布。

我还注意到 osgeo 存储库没有 edu/ucr 路径，但确实有
http://download.osgeo.org/webdav/geotools/edu/ucar/

尝试像这样回到 Maven 中央工件

  <!--added new-->
<!--<dependency>-->
  <!--<groupId>it.geosolutions.imageio-ext</groupId>-->
  <!--<artifactId>imageio-ext-jhdfaccess</artifactId>-->
  <!--<version>1.0.8</version>-->
<!--</dependency>-->

<dependency>
    <groupId>io.jhdf</groupId>
    <artifactId>jhdf</artifactId>
    <version>0.3.0</version>
</dependency>

<!--
<dependency>
  <groupId>edu.ucr.cs.jhdf</groupId>
  <artifactId>jhdf</artifactId>
  <version>0.1-SNAPSHOT</version>
</dependency>
-->
