title: keytool is not an internal or external command
body: <p>When I tried to run this command "keytool -genkey -v -keystore example.keystore -alias example -keyalg RSA -keysize 2048 -validity 10000" 
  It says  "keytool is not an internal or external command, operable program or batch file"
  I have checked the environmental variable and they are correct,
  Any help could be appreciated, thanks in advance</p>
