This morning when I opened my Eclipse workspace, one of my RCP projects had ... that is normally called 'Plug-in Dependencies' was labelled 'org.eclipse.pde. core.requiredPlugins (unbound)' and the container was empty.

  其实,这个workspace下存在sms[localhost]和sms_myself两个project,实际呢,这两个是同一个,只是project名字不同,其里面的包、类、应用库都是相同的,只不过sms[localhost]是书本配套的源码,而sms_myself是自己练习开发用的!

  无意之中发现,当这两个project中其一发生"unbound"的问题时,删除其一,则"unbound"的问题就迎刃而解!所以后来我就把重新开一个eclipse来打开源码sms[localhost],此后两个project相安无事,再也没有"unbound"!
