Question

我试图同时学习Xtend和Eclipse插件开发。我创建了一个Eclipse插件项目，并添加了三个Xtend类以在应用程序模型中实现Parts。如果我将该项目保留为基于插件的项目，并尝试从产品配置中启动它，那么一切正常。

但是，如果我将其转换为基于功能的项目并尝试从产品配置中启动它，则尝试解析Arrays.asList(Classtouse.getDeclaredFields()).forEach(Field -> FieldMap.put(Field.getName(),Field.get(//your object here)));时会出错。

这是错误日志：

这是MANIFEST.MF文件：

我一直无法弄清楚如何在功能项目中指定其他Xtend依赖关系，并需要建议。

Answer 1

如错误消息所述，您的产品不包含Guava插件。当您希望产品基于功能时，必须添加一个包含Guava插件的功能。如有必要，您可以为此定义自己的功能。

在基于功能的插件中使用Xtend
