Slf4j compatibility issues with Dropwizard and Hibernate annotations

While writing a project using dropwizard(0.7.1) and hibernate annotations(3.5.5-Final) I ran into a problem with the versions of slf4j which is a dependency of both but with different versions. dropwizard uses v1.7.6 and hibernate uses 1.5.8.

The solution was to add in the pom file the following dependency:

<dependency>

      <groupId>io.dropwizard</groupId>

      <artifactId>dropwizard-core</artifactId>

      <version>0.7.1</version>

      <scope>compile</scope>

      <exclusions>

        <exclusion>

          <artifactId>slf4j-api</artifactId>

          <groupId>org.slf4j</groupId>

        </exclusion>

      </exclusions>

    </dependency>
