How to install Maven into Red Hat Enterprise Linux 6?

The distro agnostic generic repo is what you want. As root, add a couple of the jpackage-generic repos to yum (two snippets below). Then perform a yum update and finally yum install maven2.

cat > /etc/yum.repos.d/jpackage-generic-free.repo << EOF[jpackage-generic-free]name=JPackage generic freebaseurl=http://mirrors.dotsrc.org/jpackage/6.0/generic/free/enabled=1gpgcheck=1gpgkey=http://www.jpackage.org/jpackage.ascEOFcat > /etc/yum.repos.d/jpackage-generic-devel.repo << EOF[jpackage-generic-devel]name=JPackage Generic Developerbaseurl=http://mirrors.dotsrc.org/jpackage/6.0/generic/devel/enabled=1gpgcheck=1gpgkey=http://www.jpackage.org/jpackage.ascEOF

I had all kinds of conflicts trying to use the JPackage repo with Scientific Linux 6.2, but I had much better luck with dchen's repo from the "Fedora People" unofficial repositories. The repo config I used is:

# Note: Replaced $releasever with 6Server since SL's "6.2" doesn't work[epel-apache-maven]name=maven from apache foundation.baseurl=http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-6Server/$basearch/enabled=1skip_if_unavailable=1gpgcheck=0[epel-apache-maven-source]name=maven from apache foundation. - Sourcebaseurl=http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-6Server/SRPMSenabled=0skip_if_unavailable=1gpgcheck=0

The package itself is called apache-maven and installs maven 3.0.3.

This is more updated way:

curl http://www.jpackage.org/jpackage50.repo > /etc/yum.repos.d/jpackage.repoyum updateyum install maven2
