我是第谷的新手。我正在尝试使用 Tycho 创建产品，但每次运行时都会遇到以下错误：

Cannot resolve project dependencies:

[ERROR]   Missing requirement: RCPplugin.RCPplugin 0.0.1.qualifier requires  'org.eclipse.rcp.feature.group [3.7.2.dist-8R9GFpOFUdy-521934]' but it could not be found

【解决方案1】：

您是否告诉第谷在哪里寻找依赖项？与 Maven 不同，Tycho 没有用于查找依赖项的默认存储库。您需要明确配置此搜索范围 - 所谓的目标平台 - 例如与

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

更多配置目标平台的选项可以在here in the documentation找到。
