這是遇到的問題，很明顯看到：

<strong>Missing Constraint: Import-Package: org.eclipse.equinox.internal.util.event; version="1.0.0"</strong>

這裡就是沒有載入這個jar檔案，可是看書上的說明也沒喲要求載入這個檔案啊，網上找了很多資料基本也都是指向這個問題，後來看到一篇文章也是遇到這個問題之後的解決方案，於是我就按著他的解題報告試著載入一下，果然成功運行。

下面貼張圖說明一下：

由於剛剛接觸OSGi，真的就像老師說的一樣這個技術的學習不是直線的而是曲線，有一定的難度，從一開始看到拋出異常就害怕到後來慢慢的試著自己解決問題，尋找資料還是討論，但終歸是解決了問題，真的很開心。

雖然難了一些，但現在回頭再看剛開始接觸OSGi的時候還是清晰明了了很多。
