在Eclipse的kepler中运行OSGI工程出错的解决方案
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:

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)

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:
org.apache.felix.gogo.command
org.apache.felix.gogo.runtime
org.apache.felix.gogo.shell
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:
可以看到HelloWorld bundle已经被安装并且解析完成,但是还没有启动(这是因为我设置的是不自动start);
在osgi>提示符后面输入start 1,然后再次ss,会发现helloworld bundle已经启动(ACTIVE)。
