Exception thrown while using logback/slf4j

Question

I am using slf4j 1.6.2 api jar (tried using 1.6.1 as well) - logback version is 0.9.29 (core & classic). I am using jdk1.6 on ubuntu. The exception I received is copied

Answer 1

We have to align the versions of slf4j-api and the corresponding binding, in my case I was using slf4j-log4j12, acording with the documentation of SLF4J:

http://www.slf4j.org/codes.html#version_mismatch

I replace the versions of both libraries included as transitive dependencies, putting in my pom this:

    
        org.slf4j
        slf4j-api
        1.7.1
    

    
        org.slf4j
        slf4j-log4j12
        1.7.1
    

I hope this help to somebody.

Kind regards,
