Re: HTTP/2 support in Maven
http/2 is not available before Java 8. ALPN and TLS 1.3 are requirements for h2. I saw httpClient 5 implemented http/2. That's fine and that's why you may have successfully connected tomcat with a http/2 client. Try another application server which does not use httpClient, e.g. OpenLiberty. You will not be able to have a http/2 server side protocol support. I hope this helped for clarification. Thus, I consider my previous mail *not* nonsense. If maven didn't use httpClient (which I was not aware of at time of writing), my statement would have been true: just use Java 9+ and it will connect via http/2. I am sorry this caused confusion, but I did not like your response which did sound "aggressive" to me. I will therefore not contribute to this project soon.

Re: HTTP/2 support in Maven
While TLS 1.3 and ALPN (and ciphers) may have been backported, I am not aware of http2 being backported to Java 8. Even if it was, it would not be part of EVERY JVM implementation, eg Eclipse OpenJ9.

If not: Are there any plans to add the support? There is nothing to turn on and that would be unwise, something like this should be done through ALPN. Maven uses by default Wagon HTTP Transport on top of Apache HttpComponents 4.5.x. Beginning with Apache HttpComponent 5.0 HTTP/2 is supported. One would need to write a new (updated) HTTP Transport to move all gone. There is one crucial issue needs to be solved first: HTTPCORE-626. Also read the related discussion [1]. Is there anything explicitly you expect from HTTP/2 compared to HTTP/1.1? I have done a lot of internal improvements to Wagon HTTP this year which covers a lot of use cases. Have you done testing with curl which proves some kind of improvement? I have talked about possible benefits of HTTP/2 in corporate environments with jfclere@ and he sees little benefit because when you have a repo manager in house, you have (a) a gigabit connection and (b) minimal hops between client and repo manager.
