Can not use schema-registry:register goal of the maven plugin

Hello,

When trying to register my avro schema to the schema registry with the maven plugin, as explained here: https://docs.confluent.io/current/schema-registry/docs/maven-plugin.html, I get the following error:

[ERROR] Failed to execute goal io.confluent:kafka-schema-registry-maven-plugin:4.0.0:register (default-cli) on project AvroTest: Execution default-cli of goal io.confluent:kafka-schema-registry-maven-plugin:4.0.0:register failed: A required class was missing while executing io.confluent:kafka-schema-registry-maven-plugin:4.0.0:register: com/fasterxml/jackson/core/type/TypeReference.

Here is the pom file I am using:

I've found why it was not working. It seems that the plugin does not set the jackson dependcy.

If I modify the plugin definiytion of my pom file as shown bellow, it is working.

        <plugin>
            <groupId>io.confluent</groupId>
            <artifactId>kafka-schema-registry-maven-plugin</artifactId>
            <version>${confluent.version}</version>
            <configuration>
                <schemaRegistryUrls>
                    <param>http://desbv401.belgianrail.be:8081</param>
                </schemaRegistryUrls>
                <subjects>
                    <test_ri_tt-key>src/main/avro/trainkey.avsc</test_ri_tt-key>
                    <test_ri_rt-value>src/main/avro/timetable.avsc</test_ri_rt-value>
                </subjects>
            </configuration>
            <goals>
                <goal>register</goal>
            </goals>
            <dependencies>
                <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->
                <dependency>
                    <groupId>com.fasterxml.jackson.core</groupId>
                    <artifactId>jackson-core</artifactId>
                    <version>2.9.4</version>
                </dependency>

            </dependencies>
        </plugin>

But is not preferable to modify the plugin to automatically manage this dependency?
