Maven 构建问题 - 与存储库的连接被拒绝

Question

我希望导入、更改、重建、测试和推送/ checkin 我对可用代码的更改 in this Github repository

目前，我不希望为此使用任何 IDE 或插件。

我在我的 Windows 机器上安装了 Maven，并按照如下所示的安装说明进行操作:

Answer 1

很可能你在代理后面。

尝试做一个telnet repo.maven.apache.org 80并且您可能会发现它无法连接。

在你的 settings.xml 中，添加相应的代理设置，告诉 Maven 通过代理下载 Artifact

<settings>
    .......
    <proxies>
        <proxy>
            <active>true</active>
            <protocol>http</protocol>
            <host>your_proxy_host</host>
            <port>your_proxy_port</port>
            <!--
            <username>proxyuser</username>
            <password>somepassword</password>
            <nonProxyHosts>*.yourdomain.com|*.yourOtherDomain.com</nonProxyHosts>
            -->
        </proxy>
    </proxies>
</settings>
