Giving Version / Build information in Java project

For several of my projects I capture the subversion revision number, time, user who ran the build, and some system information, stuff them into a .properties file that gets included in the application jar, and read that jar at runtime. The ant code looks like this:

<property name="version" value="1.23"/>



<target name="buildinfo">

<tstamp>

   <format property="builtat" pattern="MM/dd/yyyy hh:mm aa" timezone="America/New_York"/>

tstamp>  

<exec executable="svnversion" outputproperty="svnversion"/>

<exec executable="whoami" outputproperty="whoami"/>

<exec executable="uname" outputproperty="buildsystem"><arg value="-a"/>exec>



<propertyfile file="path/to/project.properties"

   comment="This file is automatically generated - DO NOT EDIT">  

   <entry key="buildtime" value="${builtat}"/>

   <entry key="build" value="${svnversion}"/>

   <entry key="builder" value="${whoami}"/>

   <entry key="version" value="${version}"/>

   <entry key="system" value="${buildsystem}"/>
