$ mvn -v – command not found - bash

Question

I installed Maven on macOS 10.12.6.
Added environment to .bash_profile file:
export PS1="\h --- \t *************************** \w $ "
export JAVA_HOME=$(/usr/libexec/java_home)
export MAVEN_HOME=/Users/{user}/Documents/Path/Maven/maven_3.3.9
export GRADLE_HOME=/Users/{user}/Documents/Path/Gradle/gradle_6.1.1
export PATH=$PATH:$MAVEN_HOME/bin
export PATH=$GRADLE_HOME/bin:$PATH
After that I save it and set source .bash_profile command in Terminal.
When I try in Terminal input mvn -v command I see:
-bash: mvn: command not found
When I input $MAVEN_HOME I see:
: No such file or directory/Path/Maven/maven_3.3.9
If I use echo $MAVEN_HOME command I see:
/Users/{user}/Documents/Path/Maven/maven_3.3.9
If I input this mvn I see:
-bash: mvn: command not found
JDK on Mac - $JAVA_HOME command in Terminal:
-bash: /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home: is a directory
Can you help me please to understand where I missed.

Answer 1

Thank you very much for your answers, I fixed my problem just like that:
export PATH=/Users/{user}/Documents/Path/Maven/maven_3.3.9/bin:$PATH
After that everything worked as expected.
If you think my method is not good, please tell me why?

Answer 2

Since it is a maven 2+, export M2_HOME (see "What is the difference between M2_HOME and MAVEN_HOME")
And double check what echo $PATH returns after sourcing the .bashrc.
Make sure it:
includes $M2_HOME/bin
ls $M2_HOME/bin does exists.

Answer 3

Check this
1) Review your path, I think you are missing '$' character right before {user}
2) Review execution permission for 'maven_3.3.9/bin/mvn'
3) Make sure you are using Bash as Unix shell (and not zsh or another)
echo $SHELL
# output should look like: '/bin/bash'
4) If you are using bash then add maven's ENV variables to the file ~/.bashrc (or ~/.zshrc if you are using zsh)
5) 'source' your configuration
source ~/.bashrc
Notes
I recommend understand differences between .bashrc and .bash_profile: http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html
If you want to keep your configuration on .bash_profile then just rebooting your system should be enough (to start a login shell which load .bash_profile)
