java - IntelliJ/Maven repo 问题

Question

我真的被这个问题困扰了，这是我尝试修复它的第二天。我尝试了网络上所有可用的资源(至少是我能找到的)

我正在使用 Spring MVC 并尝试启动新的 Maven 项目。发生的事情是项目是从模板构建的，这是我遇到的错误。

当我在不使用原型(prototype)的情况下构建新项目时，maven 根本无法工作 - 并出现以下错误:

1:当我检查 Maven 存储库时，我可以看到 repo.aven.apache.org/maven2 的错误:java.lang.RuntimeException: java.io.IOException: Transfer for nexus-maven-repository-index。属性失败。

2: 当我检查Maven projct 详细信息时，插件和依赖项带有红色下划线。

这里是 mvn --debug 的输出:

请帮忙

Answer 1

根据原帖评论中提供的答案，我得出的结论是贵公司使用代理拦截网络流量。本质上，它会将公司特定的证书动态添加到您访问的所有 HTTPS 站点的证书路径的顶部。

要在 Java 应用程序中信任您公司特定的证书，您必须将它添加到该应用程序使用的 java keystore 中。以Intellij IDEA为例，自带JRE，步骤如下:

1. 在浏览器中转到 https://www.google.com或任何其他 https 站点。单击地址栏左侧的锁定图标，然后按照 UI 获取有关证书路径的信息。在 Chrome 中，您可以在单击锁定图标后单击“证书”时打开的对话框的“证书路径”选项卡中查看此信息。

2. 单击层次结构中最顶层 的证书(带有贵公司名称的证书)，然后单击查看证书。单击详细信息选项卡，然后单击复制到文件。按照小 Sprite 导出一个.cer Base64编码的文件；我们将其命名为公司。请注意，这些是特定于 Chrome 的说明，但其他浏览器也有类似的步骤。

3. 转到您的 Intellij IDEA 安装文件夹，子文件夹 /jre64/bin(或/jre32/bin)，然后将 Company.cer 复制到那里。

4. 在您复制证书的 bin 文件夹中打开一个 cmd 或 PowerShell(您可以在资源管理器中的空白处右键单击，Windows 上下文菜单将为您提供一个选项)。运行以下命令:

   keytool.exe -keystore ..\lib\security\cacerts -importcert -alias Company -file Company.cer

   当提示输入密码时，请使用 changeit，这是默认的 keystore 密码。当系统提示确认添加公司证书时，还要键入 yes。

5. 重新启动 Intellij IDEA 并重试给出初始错误的操作。
