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

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...
