Question

使用Tycho 0.21我收到一条关于未定义的提供功能“org.eclipse.equinox.p2.iu”名称的错误消息。我搜索了我们的代码库中的字符串“org.eclipse.equinox.p2.iu”，并且只在P2更新站点中找到它，我只是为了再次获取相同的错误消息而禁用它。

使用包含“pom”的包含多个模块的POM时会发生错误：

<modules>
  <module>some-module</module>
</module>

早些时候使用Tycho 0.8的大量修改版本。我们目前正在尝试切换到Tycho 0.21，其中一个挑战是从基于文件系统的目标平台（Eclipse中的“安装”）转移到使用更新站点。

有人可以提供此消息的提示吗？

此错误是由没有ID的产品引起的。检查所有* .product文件是否在Product Configuration Editor的Overview选项卡上指定了ID。
