Question

我有一个RCP应用程序要开发;代码是几年前编写的，我必须完成它。我在Eclipse中导入了插件，我解决了所有依赖项，但是当我尝试启动它时，我收到了这个错误：

如果我使用向导导出一切正常，但是当我尝试启动导出的应用程序时，我得到了同样的错误。在此错误之前，我遇到了依赖项问题but I solve it。

任何人都有一些想法？感谢。

Answer 1

看起来您已将文本 run 放在需要类名的扩展点属性中。

我建议您打开ConfigurationElement类型并在第222行设置断点并在调试器中运行rcp app。您将能够以这种方式查看更多信息。

Answer 2

您正在扩展org.eclipse.core.runtime.applications扩展点，但您的扩展程序缺少应用程序元素的run子级。它应包含org.eclipse.equinox.app.IApplication实现的类名。

Answer 3

没有。来自EclipseAppHandle.run（）的“run”：来自哪里 application = getConfiguration（）。createExecutableExtension（“run”）;

Eclipse RCP找不到扩展名定义“run”
