The org.apache.maven.bridge package is not currently exposed to plugins from
maven-core (see importMavenApi in DefaultClassRealmManager) which is why you
get an exception trying to access it.
Could you use the org.apache.maven.repository.RepositorySystem component
instead? This would also be more portable since the MavenRepositorySystem
component was only recently added in 3.2.3
