# 一、问题 #

搭建spark环境 ,  创建Maven 新项目的时候，一直报错：

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6  
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

# 二、原因 #

到maven目录（在eclipse的   window->Maven->user settings 可以看到）    .m2\\repository\\org\\apache\\maven\\plugins\\maven-resources-plugin\\2.6  下,  随机选择一个文件打开。。 发现有连接超时   应该是部分依赖jar 外网不能访问到。。

# 三、解决办法： #

## 1.   配置Maven 代理 ##

### 1.1   在目录.m2  下创建 settings.xml    ###

### 1.2   settings.xml   添加下文（红色部分换为自己的外网代理和端口） ###

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"  
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0  
            http://maven.apache.org/xsd/settings-1.0.0.xsd">  
  <localRepository/>  
  <interactiveMode/>  
  <usePluginRegistry/>  
  <offline/>  
  <pluginGroups/>  
  <servers/>  
  <mirrors/>  
  <proxies>  
    <proxy>  
      <id>http</id>  
      <active>true</active>  
      <protocol>http</protocol>  
      <username></username>  
      <password></password>  
      <host>proxy.xxx</host>  
      <port>8080</port>  
      <nonProxyHosts>localhost:127.0.0.1</nonProxyHosts>  
    </proxy>  
    <proxy>  
      <id>https</id>  
      <active>true</active>  
      <protocol>https</protocol>  
      <username></username>  
      <password></password>  
      <host>proxy.xxx</host>  
      <port>8080</port>  
      <nonProxyHosts>localhost:127.0.0.1</nonProxyHosts>  
    </proxy>  
  </proxies>  
  <profiles/>  
  <activeProfiles/>  
</settings>

## 2、删除目录     .m2\\repository\\org\\apache\\maven\\plugins ##

删了，再次创建。。会再重新下载。。

## 3、 再新建 Maven 项目 ##
