Publishing Java Artifact to Nexus using Maven

Step 1: Configure Maven Settings

Open your Maven settings.xml file, typically located in the conf directory of your Maven installation or in the .m2 directory in your home folder. Add server details for Nexus in the <servers> section:

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

Step 2: Configure POM File

Update your project’s pom.xml file to include the distribution management section with details of your Nexus repository. Add the following within the <project> element:

    <distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <url>http://your-nexus-url/nexus/content/repositories/releases</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <url>http://your-nexus-url/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

Step 3: Build and Deploy

Run the following Maven command to build and deploy your artifact to Nexus:

mvn clean deploy

Step 4: Check Nexus Repository

Open your Nexus Repository Manager and navigate to the appropriate repository (releases or snapshots) to verify that your artifact has been deployed successfully.
