com.coremedia.blueprint.base.links.impl.PropertiesRuleProvider and com.coremedia.blueprint.base.links.impl.SitesRuleProvider have been deleted from the Java API, incl. the bpbase-links-legacy.xml configuration file. You probably do not use the classes directly in your project code. Instead, check if you still import the legacy configuration file in the blueprint-links.xml file in the cae-base-lib module, and eventually migrate to the AbsoluteUrlPrefixRuleProvider .
