如何解决通过 Gitlab CICD 将 Maven 项目部署到 Nexus
所以我的问题如下，我有一个新安装的 Nexus 3 实例在我的 Portainer 实例内的 Docker 容器中运行。目前我正在开发一个使用 Maven 构建的 Java 库。我想通过 Gitlab CI 将我的构建工件上传到 Nexus 以存储和重用它们。在下面，您可以找到我的 Java 项目配置、Gitlab CI 脚本以及我的 Nexus 的外观。
Nexus：

当我使用此配置运行我的管道时，除了部署之外，一切正常。在这个阶段 Gitlab 抛出一个错误：

我该怎么做才能解决这个错误？我想可能是我的存储库 URL（自托管 Nexus）错误，或者我错过了一些 Nexus 配置。我之前在工作场所使用过 Nexus，但我从未配置过 Nexus 实例，所以我可能错过了什么？
