To deploy a Java application code with source code and javadoc to a Maven Repository (like Nexus), you can use the following Maven command:

mvn deploy:deploy-file 
    -DgroupId=com.vianneyfaivre -DartifactId=your-artifact-id -Dversion=0.1 
    -DgeneratePom=true -Dpackaging=jar 
    -DrepositoryId=your-maven-repo 
    -Durl=https://your-maven-repo.com/repositories/releases 
    -Dfile=target/utility-raw-to-datahub-1.8.jar 
    -Dsources=target/utility-raw-to-datahub-1.8-sources.jar 
    -Djavadoc=target/utility-raw-to-datahub-1.8-javadoc.jar

The parameter repositoryId should be defined in the section distributionManagement of your project’ pom.xml or in your ~/.m2/settings.xml.

<distributionManagement>
    <repository>
        <id>your-maven-repo</id>
        <name>Your Maven Repository</name>
        <url>https://your-maven-repo.com/repositories/releases</url>
    </repository>
</distributionManagement>
