Answer 1

I struggled with the same issue, and the following worked for me.

Step 1: Check your JAVA_HOME setting. It may look something like:

JAVA_HOME="/usr/libexec/java_home"

Step 2: Update JAVA_HOME like so:

$ vim .bash_profile 

export JAVA_HOME=$(/usr/libexec/java_home)

$ source .bash_profile

Step 3: In a new shell, check that the Maven command is now working properly:

$ mvn -version

If this fixed the problem, you should get back a response like:
