Maven：找不到命令：mvn

Question

My maven stopped working all of a sudden. I am using macOS Catalina 10.15.6. Maven is installed in Applications directory. It was working fine for over an year. My.bash_profile has

export JAVA_HOME=$(/usr/libexec/java_home)
export M2_HOME=/Users/vn0gdpo/Applications/apache-maven-3.6.3
export PATH=$PATH:$M2_HOME/bin

Answer 1

MacOS has recently changed the default shell to zsh and the output shows you are running zsh. You now need to update $HOME/.zshrc and $HOME/.zlogin (or change your login shell back to bash : chsh -s /bin/bash ).
