我的团队正在维护一个基于Eclipse 3.8.2和Java 1.7的软件。由于我们试图添加需要Java 1.8的功能，因此我要负责将整个环境升级到Java 1.8，并且在此过程中还必须升级到新版本的Eclipse。因此，我要做的就是复制工作区，在Eclipse 4.9.0中打开它，并解决Eclipse给我带来的所有错误。除其他外，我们正在使用OSGi，在新环境中启动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，但是在该问题上找不到很多有用的材料。
无论如何，当我启动应用程序时，我从OSGi中得到了很多错误，这些包引用都无法解决。我不确定哪个清单文件需要这些捆绑包，以及如何将它们包括在内。我进行了三重检查，运行配置具有所有插件，软件的旧版和工作版都具有，所以似乎不是。
我得到的踪迹是：

我删除了很多行，因为这占用了太多空间。 迁移到新的Eclipse时，我是否犯了一个错误？我忘了修改某些清单文件吗？新的Java / Eclipse版本是否需要更改某些设置？
谢谢！
