Tycho无法连接到Eclipse p2存储库

标签： java eclipse maven tycho

我正在尝试设置Tycho，以便我可以在Eclipse-Plugin项目中使用我的Maven依赖项。在我发现的所有文档和在线教程中，您必须在某些时候将eclipse p2存储库添加到您的maven pom.xml中（否则构建将失败）。

所以我在父pom.xml中包含了以下配置：

<repositories>
    <repository>
        <id>eclipse-luna</id>
        <layout>p2</layout>
        <url>http://download.eclipse.org/releases/luna</url>
    </repository>
</repositories>

但是构建仍然失败：

我在googeling中找到的所有东西都是用-Djava.net.preferIPv4Stack = true来启动Eclipse，这对我没有解决问题。出于某种原因，我甚至无法使用我的网络浏览器访问http://download.eclipse.org/releases/luna/content.xml。我也试图找到存储库的镜像，但我刚刚找到了有关如何创建自己的镜像的教程（这对我来说也不起作用）。

现在有人在这里吗？

问题似乎是您的代理配置不正确。 Tycho使用为Maven配置的代理配置。检查Maven documentation以了解如何为Maven构建配置代理。

Tycho无法使用Eclipse配置，因为它是一个独立于Eclipse工作区运行的命令行构建工具。
