使用 tycho-p2-extras 镜像 Eclipse p2 存储库时如何获取源包

Question

我想创建一个包含构建 rcp 应用程序所需的 ius 的 eclipse p2 存储库的镜像。镜像确实有效，并且所需的包在本地存储。我可以从我的 tycho 构建和我的 eclipse ide 中引用它们。它可以工作，但包含 eclipse p2 镜像文件夹的 targetdefinition 文件抱怨缺少源包。

我阅读并尝试了 tycho-p2-extras 提供的开关，但似乎没有开关可以解决这个问题。

据我所知，tycho-p2-extras-plugin:mirror 目标中没有这样的选项，因为插件所依赖的 Eclipse 镜像应用程序中没有这样的选项。

您必须自己镜像相应的源功能（这将自动镜像所包含捆绑包的相关源）。

但是，某些项目提供了自动包含所有源的功能，例如，org.eclipse.emf.sdk.feature.group。如果您镜像此类功能，您还将镜像所有源。
