Com.haulmont are not loading in Intellij IDEA

Hi

As I open my CUBA project code in Intellij Idea the com.haulmont packages are not loading. These are displayed in red marks and it is showing as “Cannot Resolve Symbol”. Please can you fix it!

Thank You!

Hi,
Which versions of the platform and IDEA do you use? Do you use custom Gradle?

Make sure you have done everything as written here: https://doc.cuba-platform.com/manual-6.6/setup.html.
Then try to perform Build->Create or update IDEA project files in Studio and File->Invalidate Caches/Restart in IDEA.
Hope this should help.
