I met the same problem   Window 10 environment  I solved it by deleting the JAVA HOME  C  Program Files Java jdk1 8 0 161 bin  in the User Variables instead of adding to the System Variables directly   Then I test that editing JAVA HOME  C  Program Files Java jdk1 8 0 161   worked too   When I run  mvn -version  in command prompt window  it shows  Java home  C  Program Files Java jdk1 8 0 161 jre     In conclusion  I guess the JAVA HOME shouldn t include bin directory

First  ensure that the Maven bin is in your Environmental Variable PATH entry    If it is  make sure your entries aren t somehow out of order  and that JAVA HOME is before Path in the list  or any entry that references  JAVA HOME   I was getting the same error when I was trying to check my maven version   I have a few extra path variables that reference  JAVA HOME   or a different version of a JDK and Maven was mixed in between  I moved my Maven path entry below my  JAVA HOME  one and now everything is working when I use Maven from cmd   But it is Windows  so perhaps my just opening and closing the Environment Variables setting somehow made everything better

Make sure that you do NOT have a JRE path  if you have delete it     Add JAVA HOME in the System variable  Variable value  C  Program Files Java jdk-10 0 2  location of JDK without bin  Add M2 in the System variable  Variable value  C  dev maven apache-maven-3 5 4 bin  location of maven with bin  Add M2 HOME in the System variable  Variable value  C  dev maven apache-maven-3 5 4  location of maven without bin  Add  JAVA HOME  and  M2  in Path System Variable or C  Program Files Java jdk-10 0 2 and C  dev maven apache-maven-3 5 4 bin --  For windows 10  just add the location  For other version   at the end of the Variable Value field add semicolon then the location Ex    JAVA HOME   M2    I did not check if the addition or removal of bin changes the result but nonetheless this works for me
