Question

I have a strange logs from logback. All messages (each row) followed by [jar name] like this:

 13:19:45 ERROR [c.o.s.w.s.Class] lalalalal [module-version.jar]

The pattern is:

<pattern>%d{HH:mm:ss,SSS} %-5p [%c{3}] %m%n</pattern>

I’ve searched on logback site but didn’t find anything. This suffix is messing stacktrace so how can I hide it?

P.S. Sorry for my english:)

Answer 1

It is indeed a feature as others have noted. However, if needed, it can be disabled.

You can disable it by adding %ex at the end of the pattern, so %d %logger - %m%n should be rewritten as %d %logger - %m%n%ex. In your case, I think this should be the correct form, if you want to disable it:

<pattern>%d{HH:mm:ss,SSS} %-5p [%c{3}] %m%n%ex</pattern>

This might be even needed for some situations where this information causes siginificant overhead, although I would personally leave it on and rather change the environment or the IDE.

EDIT: and yes, the %exis documented.
