Using the remote goal requires configuring the remote repository
Configuring the remote repository is accomplished in the distributionManagement section of your pom. An example is below.
<distributionManagement>
<repository>
<id>ossrh</id>
<url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
</repository>
<snapshotRepository>
<id>ossrh</id>
<url>https://oss.sonatype.org/content/repositories/snapshots</url>
</snapshotRepository>
<site>
<id>github</id>
<url>https://chonton.github.com/exists-maven-plugin/${project.version}</url>
</site>
</distributionManagement>
