情况
我有一个使用 Maven 构建的 RCP 应用程序（使用 Tycho）。
当我从命令行运行反应堆构建（主 pom，见下文）时，mvn clean build它会顺利构建并且生成的可执行文件工作正常。这在首先清理本地 Maven 存储库后也有效。
但是，当我将所有项目都包含到Eclipse中并尝试从产品文件中运行项目时，我得到一个错误。
问题
启动应用程序时会出现启动画面，但随后会出现以下错误：

笔记
- 使用嵌入式 Maven 和 CLI 上使用的外部 Maven 安装都会发生这种情况。
- 我在启动之前将产品配置与定义插件同步。
- 将项目输入 Eclipse 后，Package Explorer 中看不到任何错误。
主意
因为它在 Eclipse 之外工作，所以我假设 Eclipse 元数据文件在某种程度上已损坏。或者是否需要更多文件build.properties，并且？是否需要 Buckminster 特定的文件，即使对于 Maven 也是如此？.classpath.project
注意：Maven - 更新项目...
我尝试使用 poms更新项目文件Maven-Update project...。这样做之后，整个项目都出现了错误。
查看时svn diff，似乎只有.classpath包含文件的插件文件被修改（即删除了所有有价值的信息）。jar因此，jar无法再找到 s 并且事情发生了故障。
这似乎是由另一个错误引起的。将这些文件恢复为原始文件，删除了错误，但没有解决我最初的问题......
