run mvn dependency:tree , search dependency have slf4j implementations not want, exclude them dependency exclusion like:

<dependency>     <groupid>org.someexternallib</groupid>     <artifactid>someexternallibartifact</artifactid>     <version>...</version>      <exclusions>        <exclusion>            <groupid>org.slf4j</groupid>           <artifactid>slf4j-log4j12</artifactid>        </exclusion>        <exclusion>            <groupid>log4j</groupid>           <artifactid>log4j</artifactid>       </exclusion>     </exclusions>  </dependency>
