Re: Maven 3.0.3 hanging / having timeouts often??

[Arne Tøn]

FYI: The situation described in this thread reminds me of my problem in the
thread "Initial Maven Install - repository download fails on large
files".
It seems Windows firewall and proxies have been blamed  in the past,
however after I submitted my problem I have found that running in  a VMWare
Virtual Machine can  have the same effect :).  Using the same computer
maven seem to handle repo download fine outside the VM, but inside VM
downloads of larger files usually hangs, even if the environments are not
very different: Both are Win7x64, same Java, maven and network connection.

Problems like this on Windows are frequently related to some antivirus
or firewall (Windows or another). Try disabling your antivirus and any
firewalls you may be running (including the built-in Windows
firewall).

If you are running this on a computer "at work" there can also be
transparent Internet proxies (Squid) or antivirus appliances etc
between your machine and the download site. This is less common "at
home" but I know some ISPs are caching hits etc.

Hi,

You can use "where java" in the command line to check where your java is.

That simply means you have another java in your path before the jdk1.7.0_03. 
Perhaps there is a "java.exe" file in c:\windows or something like that.

Interesting. Do you have an example of another Java application that has
network connectivity problems? Then I could try it to see if it is the
combination Java / network hardware that is the culprit.

Just for the record, my JAVA_HOME is C:\Program Files\Java\jdk1.7.0_03, but
when I run "java -version", I get "java version "1.6.0_31"". The computer in
question is a Sony Vaio laptop, with an Atheros AR9285 wireless network
adapter.

Thanks for the suggestion, but unfortunately the same behavior when running
Maven in a Windows command-line (cmd.exe).

Running "mvn -X" does not provide much useful information, as far as I can
tell, just a timeout after around 30 minutes:

I got some similar problems.

Seems that java itself or maven or any other thing is not liking my aviara
firewall or my network device. There are some other java apps that sometime
have the same connection problems resulting in timeouts. Are there any
hints what maven is doing (activate debug option) or can you simply wait to

Re: Maven 3.0.3 hanging / having timeouts often?

[arro]

Sorry for resurrecting an old thread, but I'm having the exact same problem
with Maven 3.0.4 timing out while trying to download artifacts.

Right now I'm running Maven from home, with no proxy. The problem also
occured when I tried to use the same laptop at work, with a Nexus repository
manager. I then assumed it was some kind of temporary network problem, but
since I'm seeing the same thing again, I guess it must have something to do
with the computer setup.

I'm on Windows 7 and cygwin (CYGWIN_NT-6.1-WOW64). I have removed my
~/.m2/settings.xml to see if that made any difference -- it did not. There
does not appear to be any network problem, I can download the artifacts
manually (in Firefox) just fine.

Anyone else seen this problem?

Okay, I removed a bunch of cruft from my settings.xml and odd settings that
our company has asked us to put in there. Once cleaning this up I have not
had the timeout yet. I think I am okay for a while, but will respond again
if the problem comes back and I can provide more useful information.

Running a repository manager locally is a smart idea if you are on a laptop.
Saves you the pain of reconfiguring maven when you unplug from the network.

[Benson Margulies]

Unless you can post a project to github that demonstrates differential
behavior everywhere, or use mvn -X or wireshark to deliver an analysis
of *how* 3.0.3 is hitting the network differently than 2.2.1, you're
unlikely to get much succor here.

It would really help you if you could convince your corporate
Archiva-ists to configure it to work as a cache for the internet.

Or if you quietly put a copy of Archiva or Nexus for those purposes on
your own machine :-)

[Andrew Robinson]

Archiva is being used to serve our internal packages of our company, it is
not being used to serve dependencies from internet repositories. So no I
cannot send all requests through Archiva.

It may be as simple as a linux kernel issue with e1000e driver (dell
latitude E6410). It has caused me issues in Ubuntu in 10.10 and could be
still some issues in 11.04. It is hard to say as there is not much to debug
with at this point and I am not seeing any obvious system errors or anything
to troubleshoot with.

If this was typical then we would see similar complaints from lots of
people. Clearly something is special about the way you have things
configured or something else in your environment. I'm not sure how you
expect anyone here to diagnose this class of problem.

Did you reconfigure your proxy and settings.xml so all requests are
going through Archiva? I see that as a pre-requisite before talking
about anything else.

I'm OK with the proxy. I'm confused about the Archiva repo you have
installed. I should not have said "proxy" when I really meant
MRM/Archiva. Your log shows that your build is hitting Archiva and
then also hitting repo2, repo1, and ibiblio for a metadata.xml file.

For us (and I think a lot of users of MRMs like Nexus, Artifactory,
Archiva), a large part of the reason why we are using a Maven Repo
Manager is so that we can tell all our Maven instances on all our
machines to look for ALL artifacts directly in that repo manager
(Archiva in your case). Then our governance functions can determine
which artifacts are OK to use (based on licensing and other concerns)
and which must be avoided etc.

I think the way you have things configured is less than ideal and you
may want to reconsider it. IMO all artifact access should be managed
by your Archiva instance.

They are going through my proxy, why would you think I am hitting them
directly?

I have my  setup in my settings.xml.

It is working most of the time, if it were the fact that my proxy was not
used, it would fail 100% of the time (all internet traffic must go through
our proxy at work).

Yes, Maven 3 should download artifacts in parallell. But Maven 2.2.1 also
does that (this feature was introduced in 2.1.0 IIRC). But it is likely two
different implementations.

Me too, on win7/cygwin. I thought it was a cygwin problem.

Re: Maven 3.0.3 hanging / having timeouts often?

[Alex Lopez]

Now this got me thinking, my intuition is that this might be a network 
related problem... maybe maven 2 had shorter timeouts, hence not 
appearing to hang, does Maven 3 download more than one dependency at the 
same time? Does this behavior differ from version 2? Why hitting ^C 
under such circumstances wouldn't end mvn process, instead forcing it to 
continue?

it will eventually built. It only dies when maven is trying to download

My other co-workers have not reported seeing this issue yet. Any ideas on
why maven 3.0.3 is having this problem when maven 2.2.1 does not?

FYI, we have a corporate proxy, not sure if that could be part of the
problem.

Obviously you have a proxy. Why in the world are you connecting
directly to repo2, repo1, ibiblio etc instead of just letting your
proxy hit them on your behalf?
