我使用的Eclipse版本是3.7(Indigo)
通過Eclipse的help選項，點擊“Install New Software...”彈出安裝對話框，
點擊add按鈕,在Location里輸入http://download.eclipse.org/technology/m2e/releases/1.3然后就可以選擇安裝。
如下圖所示：
這里如果m2e的版本選擇是的1.4，則會報錯：
Cannot complete the install because one or more required items could not be found.

解決方法就是：m2e的版本選擇1.3/1.2或者升級eclipse版本。
