ClassNotFoundException: pac4jRealm not found by org.sonatype.nexus.security

Description: I am encountering a ClassNotFoundException for pac4jRealm after updating to the latest version of the nexus-pac4j-plugin. The error occurs when starting the Nexus instance. This issue started after the last three commits in the repository.

Error Log:
