Hello Ekke,

If you update your working copy of logback (svn update), you should see that 
logback now references a released version of SLF4J, namely 1.5.5.

However, building SLF4J from svn as Thorbjørn suggest is also an option. Note 
that the version of logback in the trunk sometimes references a SNAPSHOT version 
of SLF4J and sometimes are released version which can be confusing initially. 
(Building SLF4J should be easy, so it's not as bad as it sounds.)

Please let us know if you need further information,

normally I'm only using the distributed jars from logback and slf4j.
perhaps you can give me the url for the 1.5.4 snapshot needed

The information you need is at
