  `<dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-server</artifactId>
        <version>2.7</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet-core</artifactId>
        <version>2.7</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-jetty-http</artifactId>
        <version>2.7</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-moxy</artifactId>
        <version>2.7</version>
    </dependency>
    <dependency>

Answer 1

dependency:analyze-duplicate Analyzes the and tags in the pom.xml and determines the duplicate declared dependencies.

mvn dependency:analyze-duplicate

Answer 2

you can use mvn dependency:tree command to find duplicate dependencies into your project.

Use the <exclusions> tag into <dependency> tag of the pom to exclude that duplicate dependencies from maven project.

<dependencies>
    <dependency>
      <groupId>test.ProjectX</groupId>
      <artifactId>ProjectX</artifactId>
      <version>2.0</version>
      <scope>compile</scope>
      <exclusions>
        <exclusion>  
          <groupId>test.ProjectY</groupId>
          <artifactId>ProjectY</artifactId>
        </exclusion>
      </exclusions> 
    </dependency>
  </dependencies>

Answer 3

Run mvn clean It will tell you your duplicate dependencies. Then delete them.
