java - Eclipse rcp 导出产品抛出 NullPointerException

Question

我有 eclipse rcp 项目，我想导出它并使其可执行。我通过产品文件导出 Eclipse 产品。结果我得到了包含插件、其他文件和 MyApp.exe 的目录，但是当我运行 exe 文件时，在日志中我收到这样的消息。也许有人可以告诉我这个异常的原因是什么？

无法找到产品 myapp.product 是此处的关键消息 - 您导出的产品似乎不包含您的产品定义(可能缺少插件)。由于找不到产品而导致崩溃。

确保您的 xxx.product 文件包含所有插件以及它们所依赖的所有 Eclipse RCP 插件(您可以使用“添加必需”按钮来解决此问题)。
