Question

我是Maven的新手，我正在尝试使用Maven 3.3构建一个项目但是我在命令提示符下使用命令mvn clean install exec：java遇到了以下错误。

[WARNING] Could not transfer metadata org.codehaus.mojo/maven-metadata.xml from/to mirrorId (https://oss.sonatype.org/content/repositories): http://http=server.proxyserver.com

我在POM.xml中更改了代理设置，而我的POM是

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>1.4.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>java</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <includeProjectDependencies>false</includeProjectDependencies>
                    <includePluginDependencies>true</includePluginDependencies>
                    <executableDependency>
                        <groupId>org.kaaproject.kaa.demo.zeppelin</groupId>
                        <artifactId>simulator</artifactId>
                    </executableDependency>
                    <mainClass>org.kaaproject.kaa.demo.zeppelin.Simulator</mainClass>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.kaaproject.kaa.demo.zeppelin</groupId>
                        <artifactId>simulator</artifactId>
                        <version>1.2.0-SNAPSHOT</version>
                        <type>jar</type>
                    </dependency>
                </dependencies>
            </plugin>

我的settings.xml是，

<proxies>
   <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>http://http=xxx.proxyserver.com</host>
      <port>8080</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
  </proxies>

非常感谢..期待听到......即使最后发布的帖子也无济于事。

我认为问题在于您的代理配置。请查看this (https://maven.apache.org/settings.html#Proxies)或this (https://maven.apache.org/guides/mini/guide-proxies.html)。

<host>应该是没有协议的主机名（已由<protocol>提供。我认为“http://http= ...”是一个错字？或者你是什么意思使用=？

你写过“我是Maven的新手”，你真的想要使用代理吗？如果是这样，您必须正确配置它。如果不只是从您<proxies>

中删除settings.xml元素

找不到前缀＆＃39; exec＆＃39;在当前项目和插件组中[org.apache.maven.plugins，org.codehaus.mojo]
