Cobertura is reporting that there are multiple SLF4J bindings in the classpath, actually both related to different versions of the logback-classic artifact:
[ERROR] SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/var/lib/jenkins/.m2/repository/ch/qos/logback/logback-classic/1.0.13/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/var/lib/jenkins/.m2/repository/ch/qos/logback/logback-classic/1.1.11/logback-classic-1.1.11.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 [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
But I have been able to find the origin of the older version (1.0.13), as it doesn't appear in the dependency tree from the corresponding maven goal:
