Import of jakarta.validation missing

I'm following and online course on Springboot MVC. I'm working with Springboot 3.1.0-M1 version, java 17 and Eclipse 2022-09.
Now the course tells me to use the annotation @Valid in the file UserResource.java for the validation of the input.
This annotation should import the library
import jakarta.validation.Valid but Eclipse does not give me this possibility: the library of jakarta.validation is not in list that Eclipse propones me. Morover, if i try to add manually that libray (jakarta.validation.*), Eclipse underlines that code line in red and tells me that The import jakarta.validation cannot be resolved.
the @Valid annotation return me the following message: Valid cannot be resolved to a type.
I tried to import the library javax.validation.Valid without results.
If i write jakarta. in Eclipse for import a libray, the system return me a lot of libraries (ie: jakarta.ammotation, jakarta.servlet) but not the validation library.

What am I wronging?
Thanks

you have this dependency spring-boot-starter-validation so it should work, try good old restart of eclipse and make sure maven did pull the dependency
