editor does not recognize imports for codes in the same module

I had the bad idea to ask to a complete rebuild of my project
and now editor does not know about other classes in the same package! (types appear in red!)
I have been trying to read all dependencies ... to no avail
there appears a suggestion to import older version of the current module in maven (but I want THIS version!)
no way to have a build ... except going directly for maven command (and there it does work)
I suspect an inconsistency between maven numbering of the modules
desesperately stuck! thanks

(another strange thing is happening: if I mark a line of code for debugging, the debug thread does not stop there -though I am sure the code is executed
I am wondering if it is not an older version of the code that gets in the debug process)
