title: SLF4J: Class path contains multiple SLF4J bindings; exclude slf4j
body: <p>I am trying to load a Video using OpenIMAJ. It does Display the Video but always shows me this Error:</p>
  
  <pre><code>SLF4J: Class path contains multiple SLF4J bindings.
  SLF4J: Found binding in [jar:file:/C:/Users/MaryLu/.m2/repository/ch/qos/logback/logback-classic/1.0.0/logback-classic-1.0.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]

  SLF4J: Actual binding is of type [ch.qos.logback.classic.selector.DefaultContextSelector]

  <p>I already checked Similar Questions but I didn't manage to solve the problem. If i understood, i need to exclude slf4j somewhere in my <code>POM.xml</code> but i don't really know in which dependency.</p>
