title: Setting ant property with bash command result
body: <p>How could I set <strong>ant</strong> property the value which is the result of bash script execution? For example, I need to have target which utilizes <strong>svn</strong> and <strong>bash</strong> utilities in order to control build execution. Speaking more specifically, target that I'm trying to create will be used to define, whether there are modified files in deployed application via command:</p>
  
  <pre><code>svn stat | awk -F ''  ' $1=="A" || $1 == "C" || $1=="M" || $1 == "D" || $1 == "R" {print $1}' | wc -l
  </code></pre>
  
  <p>I need to set the result of this command to some ${modified_lines_number} property. </p>
