title: not able to locate keytool on my mac to sign my apk file
body: <p>I've used phonegap Build to create my .apk file and i'm trying to sign it.</p>
  
  <p>I understand that I can do this with the following command:</p>
  
  <pre><code>$ keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -validity 10000
  </code></pre>
  
  <p>But when I run this in terminal I get 'command not found' ?</p>
  
  <p>I'm running this on a mac so from what I've read I have the required JDK installed ( I have xcode ) I guess it might be that the PATH is not set correctly to keytool, but I'm unable to find any simple info on resetting this. </p>
  
  <p>Any help would be hugely appreciated. I must be missing something very simple as it can not be this difficult to sign the app ?!?!</p>
