在Eclipse Java EE IDE中创建maven项目失败

Question

默认情况下，maven插件与最新的Eclipse IDE版本（例如，Mars）集成在一起。但是，在创建Maven项目时，它只会抛出以下错误：

注意：它不经过任何代理设置

无法计算构建计划：Plugin org.apache.maven.plugins：maven-resources-plugin:2.6或无法解决其依赖项之一：未能在http://localhost:8081/nexus/content/groups/public中找到org.apache.maven.plugins：maven-resources-plugin:jar:2.6已缓存在本地存储库中，除非nexus的更新间隔已过或强制更新，否则不会重新尝试解决，否则Plugin org.apache.maven.Plugin:2.6或无法解决其依赖项之一：未能找到org.apache.maven.plugins：maven-resources-plugin 2.6在本地存储库中缓存了http://localhost:8081/nexus/content/groups/public中，在nexus的更新间隔过去或强制更新之前，不会重新尝试解析

使用的工具：

Eclipse Java EE IDE for Web Developers.
Version: Mars Release (4.5.0)

下面的xml文件对我来说很有吸引力。，要做到这一点…

1在以下位置创建一个xml文件(settings.xml)C:\users\username\.m2\settings.xml

2复制并粘贴下面包含多个镜像标记的xml代码段。

<settings xmlns="http://maven.apache.org/POM/4.0.0"
