You need to add path to svn exe file to system environment  variable PATH  after that you can run command mvn from any folder  You can do it from command line cmd exe  like this  for example   set PATH  PATH  C  maven bin   Or you can got to the folder where mvn exe is  and run your command there   And you need not mvn -version  but mvn --version parameter

Shorter  mvn -v   or  mvn --version   Output    Apache Maven 3 0 5       Maven home      Java version  1 8 0 60  vendor  Oracle Corporation Java home      Default locale  en US  platform encoding  Cp1252 OS name   windows 7   version   6 1   arch   amd64   family   dos     The other command  mvn -version  works because it starts with mvn -v   You can also try mvn -v123 and you ll get the same output   Details   mvn -h   or   mvn --help   Output        -V --show-version                      Display version information                                        WITHOUT stopping build -v --version                           Display version information    Command is not recognized  Probably you are in one of the following 2 situations    You didn t add the Maven to the Path   run ECHO  PATH     amp  ECHO   in cmd to see if you are in this situation     go to Control Panel User Accounts User Accounts   or click on your photo from the start menu  click Change my environment variables click on New    and add    M2 HOME  lt your path gt  MAVEN HOME  M2 HOME  MAVEN BIN  M2 HOME  bin  click on Edit    and add the   MAVEN BIN  at the end of the Path  You added it to the Path  but you didn t open a new command prompt    open a new command prompt  because the environment variables are not updated automatically
