创建Tycho产品错误:缺少需求
提问于 2012-07-15 12:52:16
我是第谷的新人。我正在尝试使用Tycho创建一个产品，但每次运行它时，我都会遇到以下错误：
Cannot resolve project dependencies:

你告诉Tycho在哪里寻找依赖关系了吗？与Maven不同的是，Tycho没有默认的存储库来查找依赖项。您需要显式地配置此搜索范围-所谓的目标平台，例如
<repository>
<id>eclipse-indigo</id>
<layout>p2</layout>
<url>http://download.eclipse.org/releases/indigo</url>
</repository>有关配置目标平台的更多选项，请访问here in the documentation。
