Both Maven 2 and 3 fail to retrieve a <dependency> that is larger than Integer.MAX_VALUE

Hi Mark,

We use Artifactory and downloading over HTTP works Ok with it. I'll see what headers are sent in response when Maven is making a request for <dependency>.

I tried to sniff the headers when dependency is sent but it's not that easy. IEInspector HTTP Analyzer crashes, WireShark freezes and I can't see the headers. But on one occasion before HTTP Analyzer crashed I saw the correct response length header was sent. I'll try to see if there are other ways to see the headers. May be you can also reproduce this problem and sniff the traffic with better tools or better machines than mine.

URLConnection.getContentLength() is of type int, this might explain the trouble with wagon-http-lightweight.

Managed to grab headers again, before the sniffer crashed (see images attached). Yes, the correct length is sent. Was running Maven 2.2.1 and 3.0.2.

I have the same issue, using the latest maven 3.0.4. Downloads exactly 2^31-1 bytes and then stops. Also using artifactory to serve the artifact and downloading the artifact with wget works without problems.

must be fixed with https://git-wip-us.apache.org/repos/asf/maven-wagon/repo?p=maven-wagon.git;a=commit;h=b8ca4254b1f5a828e7b1347c49b5f14bbb59e30b
You can try last maven 3.1 snapshot available here https://builds.apache.org/view/M-R/view/Maven/job/maven-3.0.x/
@since build #365

I just attempted the 3.1 snapshot (build 320) and my download stalled again and gave me a bad md5 warning:

The checksum failing is when the artifact is only the Integer.MAX_VALUE size

only checksum fail but artifact is correctly downloaded ?

No – looking at the download information, it stopped downloading then checked the checksum, it failed, so it retried the download, and kept trying and only got as far at the ~1G each time, finally failing

ok I just need to find a way how to test that.
As adding such huge file in the sources tree for unit test is impossible.
