bq. Does this mean retry for connection issue is beyond the scope of maven, wagon, http client or all of them?

As mentioned by Oleg, not at all, but not in HttpClient. This would require HttpClient to pipe through the input stream, catch exceptions and handle them for you. This is best handled in client code. This has to be implemented in Wagon. It is not that easy, these things have to be considered:

* Shall this apply for GET only? Or all idempotent requests?
* Wagon triggers events on state change, this needs to added/handled
* New properties for a retry count have to be added
* Count needs to be maintained with new methods
* How to test this? One needs to send a TCP RST, I was manage to do that by killing the Tomcat process. Does not seem to be feasible in unit tests.

Unless someone makes a proposal, this will have a low priority for me since I mostly focus on bugs in Wagon.

As mentioned by Oleg, not all all, but not in HttpClient. This would require HttpClient to pipe through the input stream, catch exceptions and handle them for your. This is best handled in client code. This has to be implemented in Wagon. It is not that easy, these things have to be observed:

* Shall this apply for GET only? Or all idempotent requests?
* Wagon triggers events on state change, this needs to added
* New properties for a retry count have to be added
* Counts needs to be maintained with new methods
* How to test this? One needs to send a TCP RST, I was manage to do that by killing the Tomcat process. Does not seems to be feasible in unit tests.

>             Project: Maven Wagon
>          Issue Type: Improvement
>          Components: wagon-http
>    Affects Versions: 3.3.4
>         Environment: windows and linux
>            Reporter: Michael Medin
>            Priority: Major
>
> There are a RetryHandler and now also a ServiceRetryHandler but both seem to focus only the handshake and no the data stream.
> In our case we download large artifacts (1+Gb) over a sometimes shaky connection which causes frequent "Connection reset" issues.
> To mitigate this we started to implement retry logic based on this [https://maven.apache.org/wagon/wagon-providers/wagon-http/] document. But seems our retry handler is never invoked when the connection is reset.
> So after some digging into the source code it seems the retryhandler are only used when connecting to the server and once the connection has been established and the HTTP headers have been read there is no retry handling for the reminder stream copy.
> Looking at the code it seems non trivial to add retry for this at is split up so I wanted to know if I am missing something before looking at implementing a PR for this.
>  
> A simple way to simulate this behavior is to start a maven build with some large dependencies and during the download phase just kill the internet connection.
> If you have a RetryHandler enabled it will never be called instead you will get a stack trace along the following:
