After a discussion with @RasmusFaber, the author of the most upvoted answer to How to prevent logback from outputting its own status at the start of every log when using a layout, I decided to create a new question as the solution in that question is not applicable to my problem.
I am building a Spring Boot application by Maven.
I'd like to get rid of the log output from ch.qos.logback when I run mvn clean install. I want to disable the Logback's own status messages as shown below.
I believe I applied all the hints given here in StackOverflow (including the above mentioned question) and everywhere else. Still I cannot make my build silent.
Please notice that all the log lines are INFO, not even WARN. So it is not a problem of missing logback-access.xml file. The logback framework show an INFO message even when if does find the file - see the 3rd line. Furthermore there are other INFO messages which are just a garbage.
Logback's own status messages I want to disable
