Trouble importing from Github Packages

[EPNero]

Cannot resolve com.oliverdunk.MCJukebox-plugin:mcjukebox-plugin:2.6.8-RELEASE whenever I attempt to use mvn install

pom.xml contains the following:

        <repository>
            <id>github</id>
            <url>https://maven.pkg.github.com/oliverdunk/JukeboxAPI</url>
        </repository>

        <dependency>
            <groupId>com.oliverdunk.MCJukebox-plugin</groupId>
            <artifactId>mcjukebox-plugin</artifactId>
            <version>2.6.8-RELEASE</version>
        </dependency>

During the installation of dependencies, this error (only for JukeboxAPI) is shown:

Could not find artifact com.oliverdunk.MCJukebox-plugin:mcjukebox-plugin:jar:2.6.8-RELEASE in
central (https://repo1.maven.org/maven2) -> [Help 1]
