使用“ mvn install”命令进行Maven构建失败

Question

我试图为Cucumber-Maven报告生成和测试我的代码（如果可行），然后打开命令提示符。 我试过“ MVN清洁”，这是建立成功。 在那之后，我尝试了“ mvn install”并遇到了BUILD FAILURE（显示错误）。

这是我的pom.xml：

看起来代理问题阻止了依赖性的下载，因此请在settings.xml进行一些更改，如果不存在则创建一个。

转到c:\\users\\youruser\\.m2\\settings.xml.

<?xml version="1.0" encoding="UTF-8"?>
<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">

 <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>user</username>  <!-- Put your username here -->
      <password>pass</password>  <!-- Put your password here -->
      <host>123.45.6.78</host>   <!-- Put the IP address of your proxy server here -->
      <port>80</port>            <!-- Put your proxy server's port number here -->
      <nonProxyHosts>maven</nonProxyHosts> <!-- Do not use this setting unless you know what you're doing. -->
    </proxy>    
  </proxies> 
</settings>

我试过用日食。 我使用maven clean并安装了相同的POM文件。 一切正常。

您的C:\\users\\youruser\\.m2\\settings.xml文件似乎存在问题。 可能是代理问题，阻止了Maven下载依赖项。 请检查您的settings.xml文件。
