Everything was working fine till yesterday with Jenkins and Sonar (using Maven). Suddenly I saw below error in Jenkins logs and build fails for all projects with the same error.
[ERROR] No plugin found for prefix 'sonar' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/user/mysys/.m2/repository), nexus (http://localhost:8081/nexus/content/groups/public)] -> [Help 1]
