My issue was solved by simply refreshing the modules View > Maven Projects. There is refresh icon which refreshes your entire project(s)
How I got this error : I imported a project (Let's call this A which is main project) first and added the remaining projects (B,C,D etc) as modules to this one as I needed all my projects to be shown in one package folder. I deleted the old (A) Project and cloned it again from repo. The IntelliJ reloaded the (A) project but when I try to run, the project wasn't compiling saying "Warning:No JDK specified for module 'B'".
