Question

我第一次在eclipse luna上设置maven项目，我在pom.xml文件中遇到错误。我做了很多谷歌解决问题，但无法解决错误。

错误：

无法转移org.apache.maven：来自https://repo.maven.apache.org/maven2的maven-archiver：pom：2.6缓存在本地存储库，在中心的更新间隔过去或强制更新之前，不会重新尝试解析。原始错误：不能传输工件org.apache.maven：maven-archiver：pom：2.6 from / to central（https://repo.maven.apache.org/maven2）： repo.maven.apache.org

Answer 1

这是因为您拥有Maven默认存储库配置，可以每天更新一次存储库中的工件。

要解决此问题，您有两个选择：

使用maven build命令中的-U选项强制maven更新
删除依赖项的目录并再次运行构建命令

最后但并非最不重要的是，您可以更改存储库的updatePolicy。看一下Maven Repositories doc
