How do I install Maven with Yum?

问题:

I'm trying not to learn much about either yum or maven. I've inherited this code and I don't want to spend more time than I have to in this environment.

I've got yum. My installation "has" ("is attached too"? "knows about"?) two repos: the Amazon one and JPackage, which I understand is something of a standard. (Actually, each of those repositories consists of two sub-repositories, but I don't think that's causing the problem.)

When I asked yum to install maven2, it declined, saying it had never heard of maven2.

When I asked yum to install maven2 ignoring Amazon, it does so, but it installs Maven 2.0.9, which is fairly old. The actual pom.xml I have requires a higher version.

When I Google for Maven repositories I get repositories that Maven can use to build other things, not repositories that Yum can use to install Maven. (I did find a repository containing thing that let Maven build Yum. I think Google is mocking me at this point.)

So, all I need is the repo file that points to a repo that contains whatever I need to install Maven 2.2.1.

If it weren't for all these labor-saving devices, I could probably get some work done.

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

wget 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,

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

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

   mv apache-maven-3.0.5  /usr/local/apache-maven
   

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

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

5. Execute these commands

   source ~/.bashrc

6:. Verify everything is working with the following command

    mvn -version

You can add maven to the yum libraries like this:

wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

Now you can install maven like this:

yum install apache-maven

Once done, maven 3 will be installed and mvn -version will show you which version you've got - I had 3.2.1.

This worked perfectly for me on CentOS 6 with one exception. It installed OpenJDK 1.6 and made it the default Java version, even though I'd already manually installed JDK 8 (possibly because I'd manually installed it). To change it back use alternatives:

alternatives --config java
alternatives --config javac

and choose the correct version.

For future reference and for simplicity sake for the lazy people out there that don't want much explanations but just run things and make it work asap:

1) sudo wget https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

2) sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo

3) sudo yum install -y apache-maven

4) mvn --version

Hope you enjoyed this copy & paste session.

yum install -y yum-utils

yum-config-manager --add-repo http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo

yum-config-manager --enable epel-apache-maven

yum install -y apache-maven

for JVM developer, this is a SDK manager for all the tool you need.

https://sdkman.io/

Install sdkman:

yum install -y zip unzip

curl -s "https://get.sdkman.io" | bash

source "$HOME/.sdkman/bin/sdkman-init.sh"

Install Maven:

sdk install maven

I've just learned of a handy packaging tool called fpm recently. Stumbling upon this question I thought I might give it a try. Turns out, after reading @OrwellHindenberg's answer, it's easy to package maven into an RPM with fpm.

yum install -y gcc make rpm-build ruby-devel rubygems
gem install fpm

create a project directory and layout the directory structure of the package

mkdir maven-build
cd maven-build
mkdir -p etc/profile.d opt

create a file that we'll install to /etc/profile.d/maven.sh, we'll store this under the newly created etc/profile.d directory as maven.sh, with the following contents

export M3_HOME=/opt/apache-maven-3.1.0
export M3=$M3_HOME/bin
export PATH=$M3:$PATH

download and unpack the latest maven in the opt directory

wget http://www.eng.lsu.edu/mirrors/apache/maven/maven-3/3.1.0/binaries/apache-maven-3.1.0-bin.tar.gz
tar -xzf apache-maven-3.1.0-bin.tar.gz -C opt

finally, build the RPM

fpm -n maven-3.1.0 -s dir -t rpm etc opt

Now you can install maven through rpm

$ rpm -Uvh maven-3.1.0-1.0-1.x86_64.rpm 
Preparing...                ########################################### [100%]
   1:maven-3.1.0            ########################################### [100%]

and viola

$ which mvn
/opt/apache-maven-3.1.0/bin/mvn

not quite yum but closer to home ;)

Do you need to install it with yum? There's plenty other possibilities:

• Grab the binary from http://maven.apache.org/download.html and put it in your /usr/bn
• If you are using Eclipse you can get the m2eclipse plugin (http://m2eclipse.sonatype.org/) which bundles a version of maven

For those of you that are looking for a way to install Maven in 2018:

$ sudo yum install maven

is supported these days.

回答8:

Maven is packaged for Fedora since mid 2014, so it is now pretty easy. Just type

sudo dnf install maven

Now test the installation, just run maven in a random directory

mvn

And it will fail, because you did not specify a goal, e.g. mvn package

This is what I went through on Amazon/AWS EMR v5. (Adapted from the previous answers), to have Maven and Java8.

sudo wget https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven
sudo alternatives --config java

pick Java8

sudo alternatives --config javac

pick Java8

Now, if you run:

mvn -version

You should get:

Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T07:58:13Z)

Not just mvn, for any util, you can find out yourself by giving yum whatprovides {command_name}
