今天学习OSGI的过程中依照书上所述搭建好第一个helloworld插件project。执行的过程中出现以下所看到的的错误：

于是乎上网google发现须要同一时候引入org.eclipse.equinox.console这个bundle。赶紧照做，例如以下图所看到的

原以为就此能够大功告成，不料...，看下文（等待我的是很多其它的Exception）

实在是郁闷的慌，于是乎又開始各种search...

最终找到了终极解决方式。即再次增加三个org.eclipse.equinox.console必须的依赖bundle，各自是：

org.apache.felix.gogo.command

org.apache.felix.gogo.runtime

org.apache.felix.gogo.shell

概括一下：当Run时报错，仅仅选种org.eclipse.equinox.console时还是会报错,那时由于OSGI组建之间存在依赖关系,要使用 org.eclipse.equinox.console必须要有它须要依赖的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版本号中没有滴，预计是进一步的重构之后的缘故。

总之。依照这样的方式就能够顺利的Run了。

在osgi>提示符输入ss命令。能够看到例如以下的详情：

能够看到HelloWorld bundle已经被安装而且解析完毕，可是还没有启动（这是由于我设置的是不自己主动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）。
