Question

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

Cannot resolve project dependencies:
[ERROR]   Software being installed: RCPplugin.RCPplugin 0.0.1.qualifier
[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

有人可以帮帮我吗？

你告诉Tycho在哪里寻找依赖关系吗？与Maven不同，Tycho没有默认存储库来查找依赖项。您需要明确地配置此搜索范围 - 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>

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