Maven从Nexus下载后无法找到工件

Question

我们遇到了问题。我在jenkins上建立了工作，在建立一个项目时，它从nexus中获取了工件。但即使它下载了它们，也无法找到工件失败的工件。它只发生在我们手动导入到nexus的工件上。

任何提示？

Answer 1

我认为它还没有完全下载，你可以查看~/.m2/repository的依赖。因为它在实际情况下仅显示“下载”，它将显示下载消息。

1. 首先检查n / w设置和互联网。
2. 如果n / w不是问题，请删除~/.m2文件夹并再次重试

你看到Nexus的依赖吗？ nexus中的pom文件中的信息是否与您的pom相对应？

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：

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

并检查您的设置以访问Nexus（settings.xml）。
