Creating a LaunchDaemon for Gitblit

I want to create a LaunchDaemon on OSX Mavericks for my Gitblit, this is my file (org.gitblit.plist):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>KeepAlive</key>
    <true/>
    <key>Label</key>
    <string>org.gitblit.plist</string>
    <key>ProgramArguments</key>
    <array>
      <string>/usr/bin/java</string>
      <string>--baseFolder</string>
      <string>data</string>
      <string>-jar</string>
      <string>/Applications/gitblit/gitblit.jar</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
  </dict>
</plist>

It's not working, but when I try java -jar gitblit.jar --baseFolder data on /Applications/gitblit everything works fine. Am I missing something?

The Gitblit GO distribution comes with a shell script gitblit.sh that will work for this purpose. This is the version of the LaunchAgent plist ~/Library/LaunchAgents/org.gitblit.plist I used.

Note the addition of the WorkingDirectory key, as well as log files in case of errors.
