title: 'gpg.exe' is not recognized as an internal or external command after setting environment?
body: <blockquote>
    <p>[INFO] --- maven-gpg-plugin:1.4:sign (sign-artifacts) @ server-test-toolkit ---
    'gpg.exe' is not recognized as an internal or external command,</p>
  </blockquote>
  
  <p>I have set the environment path:</p>
  
  <blockquote>
    <p><em>%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\MinGW\msys-7.2\bin;C:\Program Files (x86)\GNU\GnuPG</em></p>
  </blockquote>
  
  <p>I run the gpg in cmd.exe in windows, it is OK. </p>
  
  <p>But when running the maven-gpg-plugin in eclipse why still popup the error:
  'gpg.exe' is not recognized as an internal or external command,</p>
