用JDK 1.8编译java:无法访问类文件...找不到类文件

Question

尽管使用JDK 1.6版本成功编译了相同的代码,但在升级到JDK 1.8之后,它将无法编译java cannot access ....class file ...as class file not found though it exists.

我在IntelliJ Idea 13 IDE中编译它,尝试使用Rebuild选项以及配置的ANT构建 - 结果相同.

任何帮助都非常感谢.

cannot access IDispatchRequest
class file for com.abc.xyz.orchestrator.dispatch.IDispatchRequest not found

此问题现已解决:).它基本上与类路径设置有关,仅适用于JDK 1.8.

例如:如果类'A'有对B类的引用而B类正在实现一个接口说'C',则JDK 1.8中的javac需要类路径上的B类和接口C,而在1.8之前只需要类路径上的B类就足够了.
