我想为“Nokia/Series60E3”设备编译 J2ME 波兰语示例应用程序“Blank”。我得到一个编译错误。我究竟做错了什么？

似乎有访问父对象的私有属性，因此无法编译。如果我尝试为“Generic/AnyPhone”设备编译它，它工作正常。

这似乎是 SourcedLazyContainer 类中的一个错误。它们引用 lastPointerPressY 和 lastPointerPressYOffset 字段，这些字段仅在设备具有指针事件时可用。它们在 Container 类中定义如下：

//#ifdef polish.hasPointerEvents
/** vertical pointer position when it was pressed the last time */ 
protected int lastPointerPressY;
/** scrolloffset when this container was pressed the last time */
protected int lastPointerPressYOffset;
/** time in ms when this container was pressed the last time */
protected long lastPointerPressTime;
//#endif

由于您的目标设备没有此功能，因此未定义这些字段。对于 Generic/AnyPhone，此功能已定义，因此构建成功。您可以尝试将“hasPointerEvents”功能添加到您的 devices.xml / custom-devices.xml 文件中，或者在您的 ant 目标中设置 Polish.hasPointerEvents 属性。
