我使用Eclipse Mars和相关模板＆＃34; RCP 3.x应用程序创建了一个空的RCP 3.x，其中包含一个视图＆＃34;将它命名为＆＃34; com.view＆＃34;。
我创建了一个功能＆＃34; com.view.feature＆＃34;与＆＃34; com.view＆＃34;相关联，最后我在＆＃34; com.view＆＃34;内创建了产品配置。
这是feature.xml的代码：

我使用功能＆＃34; com.view.feature＆＃34;集成了另一个插件。但是当我使用第三部分插件时，我有这个错误：

阅读本教程http://www.vogella.com/tutorials/EclipseJobs/article.html似乎线程之间存在问题，但我不知道如何修复它。
有什么建议吗？
