Well, launching the analysis I saw that a css file does not appear in the analysis.
This is because it has a size of 1561 kb and sonarqube understands that it is very large and does not analyze it.
Searching through the sonarqube options, I found the following option that I attached in the image.
I have increased the size from 1000 to 1600 and now it analyzes it.
Really, does this option work for all languages and is it misplaced or is it a sonar error?
