title: How to specify input parameters for <java jar="sth.jar" fork="true"/> in build.xml of Ant?
body: <p>This may be a naive question for the people who are familiar with Ant. I am new to Ant. please do me a favor. Thanks!</p>
  
  <p>I write something like this in build.xml. </p>
  
  <pre><code>&lt;target name="run"&gt;
      &lt;java jar="build/jar/sth.jar" fork="true"/&gt;
  &lt;/target&gt;
  </code></pre>
  
  <p>But, I want to put some parameters to it, like
  <code>
      java -jar build/jar/sth.jar input.txt
  </code></p>
  
  <p>How to do that?</p>
  
  <p>By the way, where could I find the specifications of build.xml grammar? like how many attributes are there? what are the other attributes rather than "jar" "fork"? </p>
