Tycho插件无法构建产品

Question

我有一个E4项目，它包含一个产品和一个插件。当使用Tycho构建基于插件的应用程序时，我会得到以下错误。

Cannot resolve dependencies of product CR-IT_client.product:
eclipse-plugin artifact with ID "CR-IT_client" and version matching "0.0.0" was not found in the target platform

上周，我编译了它，没有任何错误，但是在清除maven缓存之后，它就不再工作了。我怎么才能解决这个问题？

当再次使用缓存时，它将编译，但它将使用旧jar文件，而不是上次编译的jar文件。

当使用'mvn干净安装‘编译时，我得到以下Maven输出：

Tycho要求您有两个项目，一个用于eclipse-repository，另一个用于定义产品的eclipse-plugin。两者都应该是聚合程序POM的<modules>。然后Tycho将能够在一个mvn clean install上找到所有东西(即使有一个干净的缓存)。
