从Nexus下载后，Maven无法找到工件

Question

我们有一个问题。 我在詹金斯（Jenkins）上建立了工作，并在构建项目时从关系中获取工件。 但是，即使下载了它们，也找不到因工件而失败的工作。 它仅发生在我们手动导入到链接的工件上。

有什么提示吗？

Answer 1

我认为它尚未完全下载，您可以在~/.m2/repository检查是否存在依赖性。 因为在实际情况下它仅显示“正在下载”，所以它将显示已下载的消息。

1. 首先检查n / w设置和互联网。

2. 如果不是n / w问题，请删除~/.m2文件夹，然后再次重试

Answer 2

您在Nexus中看到依赖性了吗？ 链接中pom文件中的信息是否与您的pom相符？

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>

并在您的pom中：

<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）。
