Just adding some more info that solved the problem for me    Make sure that the  M2  and  M2 HOME  variables doesn t have the semicolon     at the end  This should only be used if there are more than one location in that path  which is not the case  Also  make sure that in the  Path  variable  there aren t any spaces between the various paths  separated by the semicolon    Thanks to Pawan Valecha and Abhijeet Sawant for the tips

Make sure that you haven t renamed some folder which falls in the path of the M2 environment variable  In case you have  then change your M2 and or M2 HOME accordingly   It doesn t matter whether M2 or M2 HOME are System Variable or User Variables as long as you are logged in with the same user under whose scope the environment variables are

Assuming you ve created the variable path for maven as follows   Under System path  click new then edit as follows   Variable name  MAVEN HOME  Variable value  C  Program Files apache-maven-3 5 3 bin  Then continue with these instructions   Under System Path  update variable path by clicking on edit and add   C  Program Files apache-maven-3 5 3 bin    immediately after   C  Program Files Java jdk 1 8 0 161 bin    remember to add semi-colon   after  bin as included above and then run your cmd prompt and type   mvn -v

I solved this by creating all under user variables  including the PATH variable   This is because the system variables do not  translate  the user variables  So if you only want to use maven in your account  you need to add another PATH variable as a user variable  not system variable

As others have done  creating new System variables M2 and M2 HOME solved the problem   Just making User variables M2 and M2 HOME on my Windows XP machine led to maven not being recognised from the command line   I then deleted the User variables  created copies as System variables and it all came to life   This was apache-maven-3 0 4 with XP sp3  So the instructions in  http   maven apache org download cgi  seem incorrect
