Icarus answered a very similar question for me. Its not using "yum", but should still work for your purposes. Try,

Copywget http://mirror.olnevhost.net/pub/apache/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.tar.gz

basically just go to the maven site. Find the version of maven you want. The file type and use the mirror for the wget statement above.

Afterwards the process is easy

1. Run the wget command from the dir you want to extract maven too.

2. run the following to extract the tar,

   Copytar xvf apache-maven-3.0.5-bin.tar.gz
   

3. move maven to /usr/local/apache-maven

   Copymv apache-maven-3.0.5  /usr/local/apache-maven
   

4. Next add the env variables to your ~/.bashrc file

   Copyexport M2_HOME=/usr/local/apache-maven
   export M2=$M2_HOME/bin 
   export PATH=PATH
   

5. Execute these commands

   source ~/.bashrc

6:. Verify everything is working with the following command

Copy    mvn -version

If you look at your yum output it looks like it's trying to install apache-maven from the epel-apache-maven repository, and this is the package that's conflicting.

This may be the result of stale yum data, so you could try yum clean all.

You can also try disabling all repo's except for base and updates

yum --disablerepo=* --enablerepo=base --enablerepo=updates install .... 

If you already have apache-maven installed then you need to remove it.
