How to install maven on redhat linux

Question

Note  When originally posted I was trying to install maven2  Since the main answer is for maven3 I have updated the title  The rest of the question remains as it was originally posted   I m trying to install maven2 on a redhat linux box using the command   yum install maven2   but yum doesn t seem to be able to find maven2   No package maven2 available   I ve run across other posts about this topic  but the answer to the following post suggests to add repos  I add said repos  but run into errors after adding them   How to install Maven into Red Hat Enterprise Linux 6   I can only access this box via command line so simply downloading maven from their website is difficult for me

Go to mirror olnevhost net pub apache maven binaries  and check what is the latest tar gz file  Supposing it is e g  apache-maven-3 2 1-bin tar gz  from the command line  you should be able to simply do   wget http   mirror olnevhost net pub apache maven binaries apache-maven-3 2 1-bin tar gz   And then proceed to install it   UPDATE  Adding complete instructions  copied from the comment below    Run command above from the dir you want to extract maven to  e g   usr local apache-maven  run the following to extract the tar   tar xvf apache-maven-3 2 1-bin tar gz  Next add the env varibles such as   export M2 HOME  usr local apache-maven apache-maven-3 2 1   export M2  M2 HOME bin   export PATH  M2  PATH  Verify  mvn -version

Pretty much what others said  but using     bash profile  and step by step  for beginners     Move to home folder and create a new folder for maven artifacts    cd    amp  amp  mkdir installed-packages  Go to https   maven apache org download cgi and wget the latest artifact    If you don t have wget installed  sudo yum install -y wget cd   installed-packages wget http   www-eu apache org dist maven maven-3 3 5 0 binaries apache-maven-3 5 0-bin tar gz  Uncompress the downloaded file    tar -xvf apache-maven-3 5 0-bin tar gz  Create a symbolic link of the uncompressed file    ln -s   installed-packages apache-maven-3 5 0  usr local apache-maven  Edit    bash profile  This is where environment variables are commonly stored     vi    bash profile Add the variable  MVN HOME  usr local apache-maven  do this before PATH variable is defined     For those who don t know vi tool  Press i key to enable insert mode   Go to the end of the line where PATH variable is defined and append the following    MVN HOME  MVN HOME bin Save changes     For those who don t know vi tool  Press esc key to exit insert mode and  wq  to save and quit file    Reload environment variables    source    bash profile  Confirm that maven command now works properly    mvn --help
