title: Keep JVM running with a JAR from the command line
body: <p>I'm running the closure templates compiler on a soy file using a watch - it just runs </p>
  
  <pre><code>java -jar SoyToJsSrcCompiler.jar  --outputPathFormat simple.js   simple.soy
  </code></pre>
  
  <p>every time the file changes. </p>
  
  <p>The problem is that it takes a long time for the jar to load up each for each run. Is there an easy way (easy=command line tool) that would keep the JVM running to make each run faster?</p>
