Windows 7 environment variable not working in path

Question

I am trying to set up some path using environment variable  I added an environment variable  MAVEN HOME  with the value  C  maven   Then in the path I added   MAVEN HOME  bin    rest   When I type  echo  MAVEN HOME   I get the correct  C  maven  printed on the screen  But when I type  mvn  which is a batch file in the  bin  directory  it can t find it   So  I manually added the entire path in PATH   C  maven bin    rest  and it was able to find  mvn  and execute it   Could someone help me what I did wrong

If the PATH value would be too long after your user's PATH variable has been concatenated onto the environment PATH variable, Windows will silently fail to concatenate the user PATH variable.

This can easily happen after new software is installed and adds something to PATH, thereby breaking existing installed software. Windows fail!

The best fix is to edit one of the PATH variables in the Control Panel and remove entries you don't need. Then open a new CMD window and see if all entries are shown in "echo %PATH%".

Also worth making sure you re using the command prompt as an administrator - the system lock on my work machine meant that the standard cmd just reported mvn could not be found when typing mvn --version  To use click  start   all programs   accessories   right-click on  command prompt  and select  run as administrator

I had exactly the same problem  to solve it  you can do one of two things    Put all variables in System Variables instead of User and add the ones you want to PATH   Or    Put all variables in User Variables  and create or edit the PATH variables in User Variable  not In System  The Path variables in System don t expand the User Variables    If the above are all correct  but the problem is still present  you need to check the system Registry  in HKEY CURRENT USER Environment  to make sure the  PATH  key type is REG EXPAND SZ  not REG SZ

I had the same problem  I fixed it by removing PATHEXT from user variable  It must only exist in System variable with  COM  EXE  BAT  CMD  VBS  VBE  JS  JSE  WSF  WSH  MSC  Also remove the variable from user to system and only include that path on user variable

Copy the value of path to notepad and check if this corresponds with the echo  path  in terminal window and make changes if needed  Then delete the old path value and paste the notepad value back in  I assume some invisible character entered there by some installation corrupted the path value

Things like having  PATH  or spaces between items in your path will break it  Be warned   Yes  windows paths that include spaces will cause errors   For example an application added this to the front of the system  PATH  variable definition   C  Program Files  x86  WebEx Productivity Tools C  Sybase IQ-16 0 Bin64    which caused all of the paths in  PATH  to not be set in the cmd window   My solution is to demarcate the extended path variable in double quotes where needed     C  Program Files  x86  WebEx Productivity Tools  C  Sybase IQ-16 0 Bin64    The spaces are therefore ignored and the full path variable is parsed properly

To address this problem  I have used setx command which try to set user level variables   I used below     setx JAVA HOME  C  Program Files Java jdk1 8 0 92   setx PATH  JAVA HOME  bin   NOTE  Windows try to append provided variable value to existing variable value  So no need to give extra  PATH     something like  JAVA HOME  bin  PATH
