无法在Mac OSX上设置Maven

Question

I am new to Mac OSX and I'm running Yosemite. I am trying to set up Maven using this official guide in order to set up a Google Cloud Messaging Backend. Here's what I did:

1) Downloaded Maven zip (version: apache-maven-3.3.9) and Unzipped it

2) As the guide says, I need to add the bin directory to my PATH variable. So I did the following in my terminal

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.9

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60

export PATH=$JAVA_HOME/bin:$M2_HOME/bin:$PATH

The terminal didn't return any response. However when I checked to see if Maven got installed using:

mvn -version

I get a message saying:

-bash: mvn: command not found

What am I doing wrong? Did I follow the steps properly to set up Maven?

EDIT:

MVN Bin Directory path is:

/Users/Earthling/Documents/Projects/MobiProject/apache-maven-3.3.9

Answer 1

The $PATH is what point where your programs are, because of that you change it in order to find mvn . Actually you are pointing $PATH to $M2_HOME/bin .

You need to update $M2_HOME to one directory level before mvn bin and before update $PATH .

If this is your mvn home:

/Users/Earthling/Documents/Projects/MobiProject/apache-maven-3.3.9

you should use this env vars:

export M2_HOME="/Users/Earthling/Documents/Projects/MobiProject/apache-maven-3.3.9"
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_60"
export PATH="$JAVA_HOME/bin:$M2_HOME/bin:$PATH"

You can also edit your ~/.profile in order to include these lines, so you don't need to type these exports whenever you open your terminal.

Answer 2

I tried all the manual steps here and still couldn't get it to work. Then I realized I can easily install it using Homebrew , much more convenient:

brew install maven

that's all you need to install maven for mac!

Answer 3

做

export M2_HOME=/Users/Earthling/Documents/Projects/MobiProject/apache-maven-3.3.9
