title: 'gpg.exe' is not recognized as an internal or external command, operable program or batch file - Maven Release Plugin
body: <p>I just got my free Sonatype Maven repo and have been attempting to do a release. However whilst trying to do this I get an error when maven-gpg-plugin attempts to sign artifacts.</p>
  
  <p>I get a ton of asterisks showing beforehand and I just press enter and then I get this issue, here's my full log: <a href="http://pastebin.com/GkLbFgBF" rel="noreferrer">http://pastebin.com/GkLbFgBF</a></p>
  
  <p>Here are the command line parameters I am attempting to use
      clean install javadoc:javadoc javadoc:jar source:jar release:clean release:prepare release:perform</p>
  
  <p>I installed gpg4win thinking that might solve this but it hasn't.</p>
