未執行Eclipse插件

我寫了一個應該在工作空間啓動時執行的eclipse插件（請參閱Executing eclipse plugin automatically）。當我使用「運行」按鈕進行嘗試時，它完美地工作。但是現在我創建了一個更新站點並通過更新管理器安裝了插件。我不知道爲什麼，但現在在eclipse工作區啓動時它不會執行。未執行Eclipse插件

這裏有什麼問題？的plugin.xml

內容：

<?xml version="1.0" encoding="UTF-8"?> 
<?eclipse version="3.4"?> 
<plugin> 
    <extension point="org.eclipse.ui.startup"> 
     <startup class="plugin.first.handlers.StartClass"/> 
    </extension> 
</plugin>

我發現了一些其他信息在/workspace/.metadata/.log：

爲什麼我得到java.lang.NoClassDefFoundError？

檢查'plugin.xml'是否包含在代碼中。 –

'plugin.xml'包含在項目中。我已將其內容發佈在我的問題中。 – wewa

缺少Probabky依賴關係。你在'workspace/.metadata/log'中看到什麼了嗎？已安裝插件的內容如何，是否完成？ – rlegendi

我自己找到了解決方案。您需要將您在項目中使用的jar添加到您的構建配置中（請參閱附圖）。
