Eclipse RCP：創建基於插件的產品配置時出錯

我是RCP開發的新手，我在創建產品配置時遇到了問題。 IDE：Eclipse Mars 4.5.1Eclipse RCP：創建基於插件的產品配置時出錯

我使用預定義的模板「RCP 3.x Mail Template」創建了一個名爲「com.ex.mail」的Eclipse插件項目。這個插件工作（啓動一個單獨的Eclipse應用程序）！

之後，我在同一個插件項目中創建了一個新的產品配置（「mail.product」）。

這是mail.product：

<?xml version="1.0" encoding="UTF-8"?> 
<?pde version="3.5"?> 
<product name="todo" id="com.ex.mail.product1" application="com.ex.mail.application" useFeatures="false" includeLaunchers="true"> 
    <configIni use="default"> 
    </configIni> 
    <launcherArgs> 
     <programArgs>-clean -clearPersistedState 
     </programArgs> 
     <vmArgsMac>-XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts 
     </vmArgsMac> 
    </launcherArgs> 
    <launcher> 
     <solaris/> 
     <win useIco="false">

當我啓動選項卡中的「概述」 mail.product使用鏈接RCP應用我有此錯誤：

可能缺少一些插件。在.product編輯器中切換到「內容」選項卡並單擊「添加必需」按鈕。 –

我以這種方式添加了所有插件。另外，在'配置'選項卡的「開始級別」框中，我通過單擊'添加推薦...'按鈕添加了其他插件。我仍然有錯誤！ – CarlosD

您是否同步了產品？該產品是否指向一個實例化的「org.eclipse.runtime.products」擴展點？應用程序是否指向一個實例化的org.eclipse.core.runtime.applications？

由於堆棧跟蹤顯示與透視圖相關的問題，我建議沒有實例化的應用程序，其屬性WorkbenchAdvisor提供了初始的Windows透視圖。

在使用「Eclipse產品導出嚮導」導出產品後，它可以在Eclipse環境下運行。問題是當我在IDE中運行產品時eclipse – CarlosD

您是否同步配置？ – alt3

是的！現在應用程序啓動時沒有菜單和窗口。在控制檯已經消失了以前的錯誤，但我總是以下消息：！ENTRY org.eclipse.e4.ui.workbench 4 0 2016-01-12 14：29：17.820 ！MESSAGE事件管理服務不可用，無法發佈事件org.osgi.service.event.Event [topic = org/eclipse/e4/ui/renderer/requestEnablementUpdate] {org.eclipse.e4.data = ALL}。 – CarlosD

使用eclipse mars，該向導實際上可以爲您創建基本的富客戶端應用程序，其中包括產品配置文件，應用程序模型文件和添加的必需插件。您不必自己創建和配置產品配置。

看看這個simple tutorial如何開始。
