有人可以帮我吗?

推荐答案

你告诉第谷去哪里寻找依赖了吗?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

Did you tell Tycho where to look for dependencies? Unlike in Maven, Tycho does not have a default repository where it looks for dependencies. You need to configure this search scope - the so-called target platform - explicitly, e.g. with

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

可以在此处的文档中找到更多用于配置目标平台的选项.

More options to configure the target platform can be found here in the documentation.
