             Summary: Wagon should retry download on server side errors
                 Key: WAGON-567
                 URL: https://issues.apache.org/jira/browse/WAGON-567
             Project: Maven Wagon
          Issue Type: New Feature
          Components: wagon-http
            Reporter: xueqian zhang


Currently wagon has a retry mechanism when there are connections issues with repository manager like maven central, artifactory or nexus, see [wagon source|[https://github.com/apache/maven-wagon/blob/dfd22586b6b934aa5a652ca32d57ed26067432fd/wagon-providers/wagon-http-shared/src/main/java/org/apache/maven/wagon/shared/http/AbstractHttpClientWagon.java#L403]] and [httpclient source|[https://github.com/apache/httpcomponents-client/blob/4.5.x/httpclient/src/main/java/org/apache/http/impl/execchain/RetryExec.java#L90]]. However, when the repo returns errors like 500 or 503, it does not. The 5xx response from the repo might be a blip and maven should retry before giving up.
