Re: Mvn commands are stalling
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!!

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 -- C:\development\workspace1\project1dir Volume in drive C has no label.

Re: Mvn commands are stalling
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. ... C:\development\workspace1\project1dir 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. [WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 84, column 15 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. Wayne
Re: Mvn commands are stalling
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

I think I may need to figure out why and how AVG affects the mvn downloads, and come up with a long term strategy to have both available at the same time, but for now I am good!) 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.

Re: Mvn commands are stalling
Thanks Wayne for making me think :) I resolved the warning by editing the pom. 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.

Re: Mvn commands are stalling
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. -Robert On Mon, 09 Jan 2012 15:39:54 +0100, Wayne Fay wayne...@gmail.com wrote: [WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 84, column 15 - To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
Re: Mvn commands are stalling
+1 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?
