在Eclipse的kepler中運行OSGI工程出錯的解決方案

今天學習OSGI的過程中按照書上所述搭建好第一個helloworld插件工程，運行的過程中出現下面所示的錯誤：

!SESSION 2014-06-09 21:04:49.038 -----------------------------------------------

於是乎上網google發現需要同時引入org.eclipse.equinox.console這個bundle，趕緊照做，如下圖所示

原以爲就此可以大功告成，不料...，看下文（等待我的是更多的Exception）

實在是鬱悶的慌，於是乎又開始各種search...

終於找到了終極解決方案，即再次加入三個org.eclipse.equinox.console必須的依賴bundle，分別是：

org.apache.felix.gogo.command

org.apache.felix.gogo.runtime

org.apache.felix.gogo.shell

概括一下：當Run時報錯，只選種org.eclipse.equinox.console時還是會報錯,那時因爲OSGI組建之間存在依賴關係,要使用 org.eclipse.equinox.console必須要有它需要依賴的OSGI組建,因此在調試時,除了選擇自己編寫的OSGI組建還要選擇上面的三個bundle。貌似這個問題在之前的Eclipse版本中沒有滴，估計是進一步的重構之後的緣故。總之，按照這種方式就可以順利的Run了。
