----------------------------------

             Summary: Using mixed versions of slf4j causes SLF4J to print to console a WARN about this
                 Key: FORGE-2531
                 URL: https://issues.jboss.org/browse/FORGE-2531
             Project: Forge
          Issue Type: Bug
    Affects Versions: 2.20.1.Final
            Reporter: Claus Ibsen
            Priority: Minor


You can reproduce by installing the fabric8 devops addon
{code}
addon-install --coordinate io.fabric8.forge:devops,2.2.63
***SUCCESS*** Addon io.fabric8.forge:devops,2.2.63 was installed successfully.
[forge-distribution-2.20.1.Final]$ deSLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/forge-distribution-2.20.1.Final/addons/org-jboss-forge-addon-maven-2-20-1-Final/slf4j-jdk14-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/forge-distribution-2.20.1.Final/addons/org-jboss-forge-addon-database-tools-2-20-1-Final/slf4j-jdk14-1.5.8.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.JDK14LoggerFactory]
{code}

And then wait some seconds then you see all the slf4j logging. As you can see those 2 addons from forge itself are using mixed slf4j versions.

1.7.5 and 1.5.8
