Debug Eclipse: Class File Editor source not found - spring

Question

Output:
The JAR file C:\Users\segreteria.m2\repository\org\springframework\boot\spring-boot\2.7.4.jar has no source attachment. You can attach the source by clicking Attach Source below:
Perhaps, I suppose the mistake lies in the fact that
A few days ago I excluded some files from the pom that were not used, but now I would like to re-insert them, but there is no typing "< exclusions > " in the pom file. I reintegrated the 'spring-boot-devtools.2.7.4.jar' file but nothing has changed.
I tried to reintegrate it in all ways, from the pom, importing the jar, I also imported the jar sources file, the file is also present in the jdk, I imported it from a folder outside the repository, but the result remained unchanged.
thanks to who helps me.
