javadoc: error - No public or protected classes found to document

Question

Am facing an issue while running javadoc in child project. There are multiple projects and they are interdependent.

While running javadoc on childproject, I recieve below error where other project classes(dependent classes for child project) are not found in classpath. javadoc: error - No public or protected classes found to document.

How can I run javadoc on childproject? Looked into javadoc options which did not help much

Thanks

Answer 1

Some javadoc options may be required.

-sourcepath to specify different child projects/directories

-subpackages to specify a base package and all its subpackages recursively

See javadoc options for details.

See javadoc examples for various possible cases.
