Dependency convergence error with Maven

I am trying to create a REST api server for a NLP library (Illinois NER tagger) using DropWizard. The following is the content of my .pom file:

<repositories>
    <repository>
        <id>sonatype-nexus-snapshots</id>
        <name>Sonatype Nexus Snapshots</name>
        <url>http://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>
    <repository>
        <id>CogcompSoftware</id>
        <name>CogcompSoftware</name>
        <url>http://cogcomp.cs.illinois.edu/m2repo/</url>
    </repository>
</repositories>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.dropwizard</groupId>
            <artifactId>dropwizard-bom</artifactId>

            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

On adding the dependency tag and repository tag corresponding to Illinois library my code is crashing with following error on mvn package

To resolve the error, you need to manage the version of the conflicting artifacts in your dependencyManagement section.

For example: To solve the issue for edu.illinois.cs.cogcomp:illinois-core-utilities you need to make an entry like

<dependency>
   <groupId>edu.illinois.cs.cogcomp</groupId>
   <artifactId>illinois-core-utilities</artifactId>
   <version>3.0.72</version>
</dependency>

in your dependencyManagement section.
