> 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#L393] 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], [httpclient default retry handler|https://github.com/apache/httpcomponents-client/blob/4.5.x/httpclient/src/main/java/org/apache/http/impl/client/DefaultHttpRequestRetryHandler.java#L154]. However,  it only captures low level connection issues. When the repo returns errors like 500 or 503, it does not retry. The 5xx response from the repo might be a blip and maven should retry before giving up.
