Class file not found in IntelliJ

Question

In IntelliJ I get this weird error when I try to compile.

Cannot find annotation method \'cascade()\' in type \'javax.persistence.ManyToOne\': class file for         


        

Answer 1

Just got this myself but non of those things were my issue. I downloaded a project from github, then opened in intelli J with the problem after trying to run a junit test.

Solution: Project Structure -> Modules -> 'Project_Name' -> Sources (tab) -> click src folder -> Mark as: Sources

This should highlight src to be blue and all the class files should be the circles with C instead of looking like normal files. Try running a test again and see if that does it.
