java-8 - OSGI Bundles 引用未解析

Question

我的团队正在维护一个基于 Eclipse 3.8.2 和 Java 1.7 的软件。由于我们正在尝试添加需要 Java 1.8 的功能，因此我的任务是将整个环境升级到 Java 1.8，并在此过程中升级到更新版本的 Eclipse。所以我所做的是复制工作区，在 Eclipse 4.9.0 中打开它并解决 Eclipse 向我抛出的所有错误。除其他外，我们正在使用 OSGi，我在新环境中启动我们的应用程序时遇到了麻烦。老实说，我对 OSGi 并没有真正的经验。我已经尝试搜索我遇到的错误，但我没有找到关于这个问题的很多有用材料。

无论如何，当我启动应用程序时，我从 OSGi 得到一堆错误，因为捆绑包引用没有解决。我不确定哪个清单需要这些捆绑包，以及我必须如何包含这些捆绑包。我已经三重检查了，运行配置是否包含所有插件，该软件的旧版本和工作版本都有，所以似乎不是这样。

我得到的痕迹是：

我删除了一堆行，因为它占用了太多空间。迁移到新的 Eclipse 时我犯了错误吗？我忘记修改一些清单文件了吗？新的 Java/Eclipse 版本是否需要更改一些设置？

提前致谢！
