1. We need to modify with nexus url inside pom.xml Inside url we need to replace repository name

    <distributionManagement>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <url>http://100.26.240.37:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
        <repository>
            <id>nexus-releases</id>
            <url>http://100.26.240.37:8081/repository/maven-releases/</url>
        </repository>
    </distributionManagement>

        <password>admin123</password>
      </server>
    <server>
        <id>nexus-releases</id>
        <username>admin</username>
        <password>admin123</password>
      </server>
    </servers>
