虽然使用 JDK 1.6 版本可以成功编译相同的代码，但升级到 JDK 1.8 后它不会编译，说java cannot access ....class file ...as class file not found though it exists.

我在 IntelliJ Idea 13 IDE 中编译它，尝试使用 Rebuild 选项和配置的 ANT 构建 - 结果是相同的。

非常感谢任何帮助。

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

这个问题现在解决了:)。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'引用了类B并且类B正在实现一个接口说'C'，那么JDK 1.8中的javac在类路径上需要类B和接口C，而在1.8之前只有类路径上的 B 类就足够了。

Build -> Rebuild Project worked for me

I had this problem when executing a function that was returning a class that i didn't had in classpath, but I just wanted to access his inner fields. e.g: container.getContent().getField() I had to import the Content class to make it work.

For me this meant I had downloaded a corrupted jar I think. Nuke ~/.m2/repository and try again...

For me, the class that cannot be accessed was inside an external JAR. The scenario was suitable with the accepted answer here.

I solved mine by adding the JAR as a dependency to the module that error was thrown. Meaning if the error was thrown from class A, and class C was not accessed, I added the JAR containing class C as dependency to the pom.xml of module containing class A.

You can use gradle to solve this problem.

Add "transitive = true" to the dependency. Just like this:

    compile('com.***.android:***sdk:1.0.2.6@aar') {
        transitive = true
    }
