使用JDK 1.8 java编译：无法访问类文件...未找到类文件

虽然相同的代码在JDK 1.6版本中成功编译，但在升级到JDK 1.8后，它不会编译，说.java cannot access ....class file ...as class file not found though it exists

我正在IntelliJ Idea 13 IDE中编译它，尝试使用Rebuild选项以及配置的ANT构建 - 结果是相同的。

任何帮助都非常感谢。

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