             Summary: Leverage smart download retries from pax-url-aether 2.5.0
                 Key: KARAF-4773
                 URL: https://issues.apache.org/jira/browse/KARAF-4773
             Project: Karaf
          Issue Type: Improvement
          Components: karaf-feature
    Affects Versions: 4.0.7
            Reporter: Grzegorz Grzybek
            Assignee: Grzegorz Grzybek
             Fix For: 4.1.0


https://ops4j1.jira.com/browse/PAXURL-337 adds _smart_ mechanism for 
consecutive download/resolution attempts.

For example, if {{org.ops4j.pax.url.mvn.repositories}} defines 10 repositories 
and 9 of them return HTTP 404 and 10th repository gives us "socket timeout", 
additional resolution attempt doesn't have to check those 9 repositories.

Also {{AbstractRetryableDownloadTask}} uses (by default) [9 
retries|https://github.com/apache/karaf/blob/master/features/core/src/main/java/org/apache/karaf/features/internal/download/impl/AbstractRetryableDownloadTask.java#L32].
 Even if this may be configured, retry task was designed for such problems as 
timeouts, or temporary unavailability of e.g., {{mvn:}} protocol handler. Using 
9 attempts (with exponentially increasing delay) is not the right way to handle 
simple ArtifactNotFoundException...
