Question

我有一个可以在AWS上运行的pom.xml，但是在代理工作之后却没有。我已经尝试了这篇文章Maven proxy settings not working中的所有内容，但没有任何效果。

以下是使用mvn help的错误：有效设置

...

以下是我的settings.xml的相关部分

<proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>10.***.0.60</host>
      <port>8080</port>
      <username>dmgp\david.blow</username>
      <password>*******</password>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
</proxies>

主机等的设置来自适用于浏览器的pac文件。有什么想法吗？

我也试过添加这个

    <extensions>
        <extension>
            <!-- this extension is required by wagon in order to pass the proxy -->
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-http-lightweight</artifactId>
            <version>2.2</version>
        </extension>
    </extensions>

到我的pom.xml并将jar添加到我的maven安装lib目录，但是得到了这个

[ERROR]     Unresolveable build extension: Plugin org.apache.maven.wagon:wagon-http-lightweight:2.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.wagon:wagon-http-lightweight:jar:2.2: Could not transfer artifact org.apache.maven.wagon:wagon-http-lightweight:pom:2.2 from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven.apache.org -> [Help 2]

您已配置为使用http代理，而Maven的输出告诉您它正在使用https。

pom.xml工作，但代理设置不起作用？
