Mvn commands are stalling
Hello,
I am a relatively new user to Maven. I have Java 1.7 and Maven 3.0.3
installed. I am trying to fix two problems:
1. The first and more critical problem is: No matter what command I try to
run, mvn starts the download and then it just stalls. The same thing
happens when I try creating a project from an archetype. I tried running
mvn help:effective-pom to resolve the warning in the snippet below, and
that command also hangs just like the others. I have to use Ctrl-C to kill
it and retry it again.
It almost seems like it is an internet connectivity problem, but I don't
see how it can be, when it can download some jars, but not the remaining
ones.
2. I would like to know how I can resolve the warning below.
Any help you can give is greatly appreciated.
Thanks much!!
AR

Do you think it is a reasonable/good error message or can be improved
somehow (with the understanding that there are limits in what we can
practically do)?
Since most of us on this list are not Maven newbies, we have trouble
looking at things from the newbie perspective sometimes. So any input
you can provide would be appreciated.

I ran into this recently while helping some family migrate from an old
eMachines running XP to a new Mac Mini with the "Migrate to Mac"
wizard software. They had AVG which I had installed a long time ago
and the wizard couldn't get through.
If you check your TCP/IP stack, you will see an AVG Miniport Driver or
something along those lines. Just click the checkbox to disable it.
This is in Networking Properties for your LAN or Wifi device. There
are other things in the list like File and Printer Sharing and Client
for Microsoft Networks. You may be able to manage this via AVG Control
Panel as well.

Posted by A R <ja...@gmail.com>.
Thanks Wayne for making me think :) I resolved the warning by editing the
pom.
I looked up the anti-virus I have, and I only have AVG which I am not able
to turn off because of insufficient privileges. I am surprised by the fact
that re-running the command gets me a bit more further in the downloads
each time. If it is an antivirus, should it not always block the same
download?
Thanks!!

Re: Mvn commands are stalling
Posted by A R <ja...@gmail.com>.
I think what Robert mentioned was the root of my problems - I did not think
to look inside the pom.xml file, and it was also because I was having
others problems and I thought erroneously that they may be interlinked.
Also, since my pom.xml was generated by maven itself, it did not occur to
me that it may need to be edited. I was subconsciously thinking "Maven
generated it for me, I need not touch it, it must be good"....
Thanks for all your help. I really appreciate your time and ideas!!

Another observation I might try to append to Robert's list is how to separate the signal from the noise. My personal opinion is that Maven is pretty chatty, which is great for experienced users, but a bit overwhelming for some new users.
One option would be to reduce verbosity, but that doesn't really serve experienced users well. Another option would be what Karaf has done and that is to use colorized logs. http://blog.uncommons.org/2006/04/09/colour-coded-console-logging-with-log4j/ covers the gist of it. The ANSI colorization characters are kind of ugly in terminals that aren't set up correctly, but it might help improve readability?

Good comments.
Might not be a bad idea to add a suggestion "Probable cause is missing
version in your pom.xml " or "Probable cause is bad dependency
definition for org.apache.maven.plugins:maven-compiler-plugin at line 85."
I am not sure how the column number helps. What would be at column 15 of
line 85 in this case?

Hi,
Even though I'm not a newbie, I can see 2 potential problems with this
sentence:
1. line 84, column 15 of what? It doesn't mention the file. Sure, it
always about the poms, but we're talking about unexperienced users here.
2. build.plugins.plugin.version ? This doesn't look like xml, so maybe
you're not triggered to look inside the pom. And if you use a pom-editor,
you may have never seen the xml.

This kind of problem is nearly always related to some antivirus software
running on your Windows machine or on your network somewhere. Try turning
it off or whitelisting the Java.exe process.

Well let's do a thought experiment. What do you think (as a new user to
Maven) that error message means? As an experienced Maven user, it is super
clear to me, but I'd like to hear what you are thinking.
