找不到 Mvn 命令？

Question

I was working on my maven installation and was messing with a few variables to fix an error and now seemed to have lost it altogether. My PATH variable is set up correctly along with my JAVA_HOME, but I still get

-bash: mvn: command not found

I tried deleting the maven files and re-downloading them and opening a new terminal, but no luck. Are there any other trouble shooting techniques I can run through to hopefully figure out my problem. I am running on a Mac.

I had a similar issue, having, mvn not found after installing with sdkman. If you installed with sdkman just like me, you may want to execute: sdk use maven version eg:

$ sdk use maven 3.6.3


# Install skman.
$ curl -s "https://get.sdkman.io" | bash
$ source ~/.sdkman/bin/sdkman-init.sh

# Check available maven versions:
$ sdk list java
$ sdk list maven

# install desired candidate and version
$ sdk install java 13.0.1-open
$ sdk install gradle
$ sdk install maven
$ sdk install springboot


# Verify Installation by checking versions:
$ java -version
$ gradle -v
$ mvn --version
$ spring --version

If it is linux machine and you install directly using yum, then you could find the maven in /usr/local

So you can set the MAVEN_HOME in ~/.bashrc and do source ~/.bashrc to make it permanent.

Do check by $echo MAVEN_HOME and $echo JAVA_HOME

If you get exact path of both, then it will be fine.

Check that, don't forguet to restart the machine
