mvn -version is displaying -bash: /usr/local/bin/mvn: No such file or directory. Any idea how I can fix this?

Question

I was trying to upgrade from Maven 2 to Maven 3.1 on os x mavericks. I tried using brew install maven, thinking it would upgrade maven to the latest version. However that didnt help. It showed the same No such file or directory message. Following this,I uninstalled the maven(installed through brew) by doing brew rm maven.

However, now I cannot seem to get back either version of maven when I try mvn -v, I get thhe output -bash: /usr/local/bin/mvn: No such file or directory

The following is the content of my bash_profile

export M2_HOME=/usr/local/apache-maven-2.2.1/
export JBOSS_HOME=/Applications/whp-jboss-cluster-5
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/

export TOMCAT_HOME=/Library/Tomcat/
export PATH=$PATH:$M2_HOME/bin:$JBOSS_HOME/bin:$JAVA_HOME:$TOMCAT_HOME

Any idea on how I can fix this and get to maven 3 would be appreciated.

Solution

It looks like you have all of the necessary ingredients. You simply need to source your profile so that those changes take effect. (You can do this with . ~/.bash_profile.)

It is possible that your shell cached a previous version of mvn. This can happen if you add an item to your path after something of the same name has been used before. In that case, as Etan pointed out in the comments, you can just hash -r, to clear things up. (This doesn't seem to be what you were seeing, but is worth trying in the future if you add maven 3 and mvn -version keeps showing version 2.)

To get Maven 3 running, it should just be these steps. Just, with your path having the maven 3 directory instead of the maven 2 one.

I was trying to delete an old maven version when I faced this issue. the hash -r solved the problem for me after deleting the mvn folders. +1
