Gradle will not build from cmd prompt

Gradle shows up in echo %PATH% no prob… has it’s own directory … Program Files… however when i attempt gradle -v … response: ‘gradle’ is not recognised as an internal or external command, operable program or batch file…

Trying to get this to work in conjunction with an Eclipse Simpleservlet project…

thanks
