Maven resolved commons-collections groupid as org.apache.commons.collections and can't find version 3.2.1

in my pom I have a dependency:

<dependency>
    <groupId>commons-collections</groupId>
    <artifactId>commons-collections</artifactId>
    <version>3.2.1</version>
</dependency>

IMHO This is the correct dependency (compare http://mvnrepository.com/artifact/commons-collections/commons-collections/3.2.1).

However when Maven tries to resolve this, the URLs it trying for are:

Those all fail, as (IMHO) it is the wrong group id (org/apache/commons). Where does it get the "org/apache/commons" in the URL path from ?

I have no other dependency that would even mention org.apache in the group id.

Where does Maven get this URL from ?

It is just so wrong, why can't it resolve it correctly to: http://central.maven.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jar

?

My Maven setup is:

Apache Maven 3.0.4 (r1232337; 2012-01-17 21:44:56+1300)
Maven home: /home/solnet/apache-maven-3.0.4
Java version: 1.7.0_11, vendor: Oracle Corporation
Java home: /home/solnet/jdk1.7.0_11/jre
Default locale: en_NZ, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-358.2.1.el6.x86_64", arch: "amd64", family: "unix"

This is my repository setup in the pom file:

    <repositories>

        <repository>
            <id>mvnrepo</id>
            <name>mvnrepo</name>
            <url>http://mvnrepository.com</url>
        </repository>

         <repository>
            <id>centralmvn</id>
            <name>centralmvn</name>

        </repository>
        <repository>

        </repository>

   /repositories>

And this is the output of "mvn help:effective-pom" ... too big for stackoverflow so see: http://pastebin.com/RHAkUmMu

And this is the output of

mvn dependency:tree -Dincludes="org.apache.commons:commons-collections"
