Thanks Ron, Working through Eclipse is definitely superior. Turns out it has identified some of the jar files as being corrupted (commons-collections among those). Trying to delete the bad ones and trying again. At least I am making progress.... -- john
------------------ I would suggest downloading Eclipse/STS since it comes with a fully configured and properly set up Maven. Use the Eclipse - New=>Project to get started. It looks like it is a problem with that plug-in. We never use it so I can not give you much help on that and you don't need it anyway. If you want to battle Eclipse later, you can install it but we started with Eclipse and got so pissed off with the process of configuring Eclipse that we moved to Eclipse/STS for the same price. At least, you will know if it is a network problem or a maven configuration issue or a plug-in that has a problem.

Hi Ron, I can run "mvn clean" once I've gotten a sample pom file and that works fine. I've never gotten "mvn archetype:generate" to run successfully, that and other targets blow up with the problem finding the ExtendedProperties class in the commons-collections jar. So far I've been working mainly from the command line (Windows Command Prompt and Cygwin shell). Figured I would try the Maven basic "hello world" application first and move on from there. Planning to move into the Eclipse environment once I get that working. The network folks are going to get with me this afternoon to see if they notice anything in the network traffic that seems odd (or is being blocked). I would have thought that if the jar made it into the repository on my machine that the software would subsequently have been able to find it. It'll probably boil down to some Windows directory structure bs, that's my guess. In any case, thanks! -- john ------------------------- Is it only when you run this one plug-in. Does maven clean work Are you using Eclipse or some IDE to develop your code? (Eclipse/STS from Springsource comes ready to run maven). ________________________________ From: Kammer, John Sent: Thursday, December 20, 2012 4:58 PM To: [email protected] Subject: RE: RE: Newbie problem getting basic functionality to work. Thanks Wayne, Double checked with the network guys here and they assured me we are not behind a proxy. At this point I am just confused. Have tried various versions of Java and Maven only to have this same problem with commons-collections.ExtendedProperties. Oddly, I can find the jar file in the repository directory and identify the class in the jar file so I don't know why Maven thinks it can't find it. I'll probably try this at home on my laptop just to see if it makes a difference. Meanwhile, are there other interfaces to this mailing list? I would have liked to hit a reply button but seem to have only found the archive view. Thanks again, and if anyone has other suggestions what to look at/for in resolving the first problem those would be appreciated. -- John ---------------------------- > I am completely new to Maven and trying (without success) to get the most > basic of Maven functionality to work. > Have tried multiple versions of Maven and Java all with the same results (see > below). > It seems the Apache Commons Collections jar is missing, and for some reason > not being downloaded.

This is well documented on the Maven site and various free Maven ebooks, and easily found with Google etc so I won't repeat the instructions here.

Hello, and thanks in advance for any help. I am completely new to Maven and trying (without success) to get the most basic of Maven functionality to work. Have tried multiple versions of Maven and Java all with the same results (see below). It seems the Apache Commons Collections jar is missing, and for some reason not being downloaded. Any ideas why or what I can do about it? The basic operation I am attempting is to run == mvn archetype:generate Which results in…. [INFO] Scanning for projects...
