Question

我对eclipse比较陌生，我需要开发一个Javacard应用程序。我得到了eclipse neon和JDK8 + Java卡开发套件。我已完成所有教程安装，直到此页面（包含）https://docs.oracle.com/javacard/3.0.5/guide/eclipse_java_card_plug-in.htm#JCUGC127但是当我从javacard目录导入项目示例时，它告诉我（例如对于Hello World一个）：

APDU cannot be resolved to a type   
HelloWorld.java /HelloWorld/applet/src/com/sun/jcclassic/samples/helloworld line 65 Java Problem

Util cannot be resolved HelloWorld.java /HelloWorld/applet/src/com/sun/jcclassic/samples/helloworld line 78 Java Problem

我和其他项目的输出相似。我尝试了一些“解决方案”，我用谷歌搜索清理项目等，但没有人解决这个问题。我会很感激可能会发生什么以及我该怎么做的一些提示。

提前致谢。
