None of the 13 existing answers worked for me. However, I could resolve the issue by first removing all modules:

1. open File > Project Structure...,
2. go to Modules tab,
3. select all modules and press the remove button,

then removing all remaining Maven modules from Maven tool window:

1. select all modules,
2. right click on them,
3. press Remove projects,

and then adding them again in Project tool window:

1. right click on root pom.xml,
2. press Add as Maven project,

now unignoring any ignored modules from Maven tool window:

1. select all ignored (grey) Maven modules,
2. right click on them,
3. press Unignore,

and finally rebuilding using Build > Rebuild project. This assumes that a mvn clean install already happened.
