Javadoc 8 cannot find class in @see link, but java 7 did

Question

I previously asked this in javadoc 8 can not find the class in the @see link, but java 7 did , but it looks like a dead forum .:(

I have a project with several related projects. Two of the projects are executable banks with a third, Tools, which are classes of two sections. There are problems compiling tools in javadoc, and I don’t understand why. This only happened after switching to Java 8. I never saw this problem with Java 7. The classes I refer to @see are the correct syntax and name. But each @see to one of the other jars leads to an error, and the javadoc tool returns an error, and not followed. If I contact other banks with javadoc tools, @see works fine.

Can someone tell me what is going on? I added the -link commands, which the javadoc tool seems to be accepting, but it still cannot find these classes. This does not seem to be a problem with my IDE (NetBeans), as the error comes from javadoc itself.
