Publish snapshot and release both to Nexus using maven

Question

I have followed the blogs Maven Nexus Deploy and Maven Nexus Release to enable publishing my builds of modular Spring Boot application in Nexus. I am using Nexus opensource and Maven 3.6.0

My plan is to have a setup where I can publish both snapshots and releases based on the maven goal I am running. My current pom contains following details -

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

            </plugin>

                        </execution>
                    </executions>
                    <configuration>
                        <serverId>nexus-releases</serverId>
                        <nexusUrl>http://localhost:8081/nexus/</nexusUrl>
                        <skipStaging>true</skipStaging>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

My maven settings.xml contains the server entries -

<server>
    <id>nexus-releases</id>
    <username>deployment</username>
    <password>deployment</password>
</server>
<server>
    <id>nexus-snapshots</id>
    <username>deployment</username>
    <password>deployment</password>
</server>

When I run command

mvn -B release:clean release:prepare release:perform -Darguments="-DskipTests -Dmaven.javadoc.skip=true"

it works fine and my release build is uploaded to Nexus releases path.

My questions are -

Which command should I run so that my snapshot builds are created and uploaded to Nexus snapshots path?
If the command is mvn clean deploy I tried it and it still doesn't upload snapshot to Nexus. Output for deploy step in above command is -

[INFO] --- maven-deploy-plugin:2.8.2:deploy (default-deploy) @ company-service --- [INFO] Skipping artifact deployment

EDIT 1 -

I ran mvn clean deploy -X and the logs for deploy plugin are -

If you change the version of the asset you're deploying to include -SNAPSHOT it will automatically use the snapshot repository.

For example 6.2.0 will go to the release repo when you do mvn deploy or your release command.

And 6.2.0-SNAPSHOT will go to the snapshots repo when you do mvn deploy or your release command.

Also remove this:

<configuration>
    <skip>true</skip>
</configuration>

From you maven-deploy-plugin and you'll be off and running!
