使用JFrog Artifactory的Maven私有内部存储库不会自动下载所需的插件
使用JFrog Artifactory的Maven私有内部存储库不会自动下载所需的插件
提问于 2020-05-20 05:43:05
我已经创建了一个专用本地Maven存储库，用于从Central服务器处理依赖关系。我从JFrog的Maven示例中获取了一个示例项目来构建示例项目。
我遵循了设置存储库的所有步骤，并能够对其进行组装和运行。当我试图构建从https://github.com/jfrog/project-examples下载的应用程序，并且项目是maven-示例时，我会得到以下错误。
**root@xyz:/home/asdf/Downloads/mavenrepository/project-examples/maven-example# mvn deploy -U**

[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException我已经运行了maven命令mvn部署-U来尝试下载插件并将其上传到libs发行版，但是它没有工作。
我也尝试使用maven命令mvn dependency:purge-local-repository，但这也没有更新所需的插件。
现在，我们如何让maven在构建插件时再次下载所有插件并将这些插件上传到JFrog Artifactory。
还如何配置Maven settings.xml以下载JFrog Artifactory /私有内部Maven Repository中不可用的插件，并从Maven Central Server获得它--也就是说，如果私有内部Maven Repository中没有依赖项，Maven应该从Central下载它。
请帮忙支援。

根据问题中提供的跟踪，问题似乎是如何访问JCenter公共存储库。
跟踪中的以下行显示了本地缓存中请求的工件，并且Artifactory试图从JCenter请求它，但假设它脱机：
2020-05-26T10:32:01.115+02:00 Searching for the resource within jcenter
2020-05-26T10:32:01.116+02:00 Unable to find resource in jcenter-cache:org/apache/maven/plugins/maven-install-plugin/2.4/maven-install-plugin-2.4.pom
2020-05-26T10:32:01.116+02:00 Repository is assumed offline and the resource doesn't exist in the local cache - returning unfound resource这意味着Artifactory没有成功地到达jcenter几次，并最终将其标记为脱机。
这可能有几个原因，包括注释中所建议的防火墙，它正在阻止向JCenter发送的流量。
对其进行故障排除的最佳方法是从存储库配置中获取JCenter存储库URL，并确保您有网络访问它的权限。
关于JCenter，有一件事值得注意--最近，出于安全考虑，它启动了强制使用安全HTTP (https)。您的配置可能仍在使用非安全HTTP，这可能导致请求失败。
