今天学习OSGI的过程中按照书上所述搭建好第一个helloworld插件工程，运行的过程中出现下面所示的错误：

于是乎上网google发现需要同时引入org.eclipse.equinox.console这个bundle，赶紧照做，如下图所示；
原以为就此可以大功告成，不料...，看下文（等待我的是更多的Exception）

实在是郁闷的慌，于是乎又开始各种search
终于找到了终极解决方案，即再次加入三个org.eclipse.equinox.console必须的依赖bundle，分别是：
概括一下：当Run时报错，只选种org.eclipse.equinox.console时还是会报错,那时因为OSGI组建之间存在依赖关系,要使用 org.eclipse.equinox.console必须要有它需要依赖的OSGI组建,因此在调试时,除了选择自己编写的OSGI组建还要选择上面的三个bundle。貌似这个问题在之前的Eclipse版本中没有滴，估计是进一步的重构之后的缘故。总之，按照这种方式就可以顺利的Run了。
在osgi>提示符输入ss命令，可以看到如下的详情：
