If the code in that jar is all using the same package name (which is commonly how it’s done), then you can do it like this:

In logback.xml, add:

<logger name=“com.foo.bar” level=“ERROR” />

Then only error messages will be printed for classes in sub packages of com.foo.bar

I am using slf4j over logback in java.
How do I eliminate logging from a specific jar?
It prints a lot of info and I want to raise only its level to debug.
