Maven 从 Nexus 下载后找不到工件

Question

我们遇到了问题。我在 jenkins 上设置了工作，并在构建项目时从 nexus 获取工件。但即使它下载了它们，作业也因找不到工件而失败。它只发生在我们手动导入到 nexus 的工件上。

有什么提示吗？

Answer 1

好像还没有下载完整，可以去~/.m2/repository查看依赖。因为在实际情况下只显示"downloading"所以会出现downloaded message.

首先检查 n/w 设置和互联网。
如果 n/w 不是问题，请删除 ~/.m2 文件夹并重试一次

您看到 Nexus 中的依赖项了吗？ nexus中的pom文件中的信息是否对应你的pom？

http://nexusUrl/nexus/content/repositories/central/checkstyle/checkstyle/4.1/checkstyle-4.1.pom

<?xml version="1.0"?>
<project>
                <modelVersion>4.0.0</modelVersion>
                <groupId>checkstyle</groupId>
                <artifactId>checkstyle</artifactId>
                <version>4.1</version>
                <dependencies>
                               ...
                </dependencies>
</project>

在你的 pom 中：

<dependency>
                <groupId>checkstyle</groupId>
                <artifactId>checkstyle</artifactId>
                <version>4.1</version>
</dependency>

并检查您的 Nexus 访问权限设置 (settings.xml)。
