我正在尝试在 Liferay 中构建简单的第一个插件项目。我已经从其 site 下载了 Liferay 的 Eclipse 。当我使用 maven pom.xml 构建项目时，出现错误。下面是 pom.xml 的详细信息和错误详细信息。

帮助/建议任何解决方案。如何解决。
最佳答案
你的问题是
Could not transfer artifact org.apache.jackrabbit:jackrabbit-core:jar:2.1.2 from/to central (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven.apache.org -> [Help 1]
可能重复: Error in resolving buildtime dependencies while installing CloudStack on ubuntu. 或者 Maven install error: Dependency could not be resolved
检查您的settings.xml存储库位置和代理。
