我正在构建从ACtion一书ActiveMQ中获得的代码。当我使用这些命令mvn clean install运行代码时，会在下面显示这些消息。我不明白为什么要从release.openqa.org下载spring框架，因为在POM.xml的任何地方都看不到这样做的配置。
........ 从release.openqa.org下载：http://archiva.openqa.org/repository/releases/org/springframework/spring-core/maven-metadata.xml [警告]无法从/向release.openqa.org（http://archiva.openqa.org/repository/releases）传输元数据org.springframework：spring-core / maven-metadata.xml：连接至archiva.openqa.org:80 [archiva.openqa。 org / 199.102.165.92]失败：连接超时：连接 .......

在本地存储库C：\ Users \ wmunlai.m2 \下，我确实看到了一些名为“ resolver-status.properties”的文件。这可能是原因吗？我是否可以知道此文件“ resolver-status.properties”的用途。该文件之一的内容如下所示：

答案 0 :(得分：1)
存储库在pom.xml文件（您自己的一个或从属文件）或settings.xml中配置
您可以通过运行mvn help:effective-pom或mvn help:effective-settings来检查文件的有效使用。回购可能会出现在此处。由于弹簧依赖关系通常是从中央获取的，因此可能是设置问题。设置文件可以直接放置在maven安装中，也可以放置在用户的home / .m2目录中，或者通过参数传递到构建中。因此，只需在通常的Maven目标之前添加帮助目标，然后搜索回购名称即可。如果未显示您所使用的依赖项之一，可能会有些奇怪吗？然后，我将在本地Maven存储库中搜索该uri。
不再鼓励将存储库添加到pom.xml文件中，因为它们经常移动太频繁并影响构建的可靠性。通常，公司会安装Nexus或Artifactory之类的存储库镜像。两者都可以通过在settings.xml中配置为mirrorOf来工作，并代理所有发出的请求。
