新版本Eclipse Luna(4.40)安裝Activiti Designer報錯，折騰了一下午終于搞定，特記錄如下：
采用線上安裝Activiti Designer 位址為：http://www.activiti.org/designer/update/
步驟如下：
1.”Help” –>”Install New Software…”
2.安裝過程中會産生如下錯誤：
Cannot complete the software install because one or more required items could not be found.
Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
Missing requirement: Activiti Designer - GUI 5.14.1 (org.activiti.designer.gui 5.14.1) requires ‘bundle org.eclipse.emf 0.0.0’ but it could not be found
Cannot satisfy dependency:
From: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
To: org.activiti.designer.gui [5.14.1]

解決方案：
**
（1）、更新最新的emf-validation-Update-1.8.0.zip插件包，下載下傳位址：https://eclipse.org/modeling/emf/downloads/?project=transaction
離線安裝：
（2）、将如下四個檔案複制到Eclipse 的plugin目錄下
com.ibm.icu_4.4.2.v20110823.jar
com.ibm.icu.source_4.4.2.v20110823.jar
com.ibm.icu.base_4.4.2.v20110831.jar
com.ibm.icu.base.source_4.4.2.v20110831.jar
重新開機Eclipse之後線上安裝就沒問題了
