java - Eclipse RCP找不到扩展定义 "run"

Question

我有一个 RCP 应用程序需要开发；该代码是几年前编写的，我必须完成它。我在 Eclipse 中导入了插件，解决了所有依赖关系，但是当我尝试启动它时，出现此错误:

如果我使用向导导出一切正常，但当我尝试启动导出的应用程序时，我收到相同的错误。在此错误之前，我遇到了依赖项问题，but I solve it .

有人有什么想法吗？谢谢。

看起来您已将文本 run 放置在需要类名的扩展点属性内。

我建议您打开 ConfigurationElement 类型并在第 222 行设置断点，然后在调试器中运行您的 rcp 应用程序。您将能够通过这种方式看到更多信息。
