Getting -bash: mvn: command not found

问题

I tried setting the Maven PATH in .profile file as well using export commands in terminal(Mac OSX). But, on running mvn commands, getting -bash: mvn: command not found

Please help.

What did you set up exactly? Did you setup PATH like this (or something equivalent):

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

If yes, did you logout and login again? According to the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc.

As you can see, commands from .profile are not executed for a non-login shell (the type of shells you open after logging in). So you have to logout/login or to source the file manually to take your setup into account. See this blog post for more details.

Have you installed Maven, already? If you use MacPorts to install Maven, you won't need to edit your PATH.
