运行'mvn package'命令时，Maven无法正常工作

时间：2015-06-16 07:26:29

标签： java maven-3

我正在使用Eclipse开发Spring mvc。到现在为止我使用ant来创建war文件。但现在我切换到了Maven。我已经在我的系统上复制了Maven 3.3并为Maven设置了系统变量。当我从命令提示符下运行Maven时，它工作正常：

mvn -version

我在Spring mvc app的根目录下创建了一个pom.xml文件。我通过命令提示符运行Maven，而不是通过Eclipse。当我运行以下命令时：

mvn -X package

它显示以下错误：

它说连接超时，但我的互联网运行良好。

答案 0 :(得分：2)

199.27.79.215不是repo.maven.apache.org的正确IP地址。正确的IP地址为23.235.40.215 （截至2015年10月9日，来自我的桌面）。如果我打开浏览器https://199.27.79.215/，我会看到一个显示unknown domain: 199.27.79.215的网页。

问题是Maven是在没有直接连接到Internet的环境中运行的。 Maven需要配置为通过HTTP代理。找到了Maven文档here。这是信息......

  

配置代理

     

您可以配置代理以用于部分或全部HTTP请求   与Maven。只有您的代理才需要用户名和密码   需要基本身份验证（请注意以后的版本可能支持   将您的密码存储在安全的密钥库中 - 同时，   请确保您的settings.xml文件（通常   $ {user.home} /.m2 / settings.xml）使用适当的权限进行保护   适用于您的操作系统。）

     

nonProxyHosts设置接受通配符，每个主机不接受   代理由|分隔字符。这与JDK匹配   配置等价。

<settings>
  .
  .
  <proxies>
   <proxy>
      <id>example-proxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.example.com</host>
      <port>8080</port>
      <username>proxyuser</username>
      <password>somepassword</password>
      <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
    </proxy>
  </proxies>

</settings>

您正在使用

中提供的存储库 
repo.maven.apache.org:443 [repo.maven.apache.org/199.27.79.215]

并且正如错误所述，maven无法访问该网址：

org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/199.27.79.215] failed: Connection timed out: connect -> [Help 1]

检查您的互联网连接，确保您能够访问回购。您可以尝试在浏览器中使用curl或使用curl

来测试它

我发现设置我的MAVEN_OPTS环境变量有效。显然JDK7有一些问题：https://issues.apache.org/jira/browse/MNG-5162 

export MAVEN_OPTS="-Djava.net.preferIPv4Stack=true"
