title: Using ant XJC in gradle to compile multiple XSDs from JAR
body: <p>So I am able to generate classes from ONE xsd in the contract jar, using ant xjc.
  How can I generate classes from multiple schemas from this jar <strong>without unpacking it</strong></p>
  
  <pre><code> ant.xjc(package: packageName, destdir: project.ext.generatedSrcDir,    
   extension: 'true',
   schema: "jar:file:///$pathToContractJar!/MySchema.xsd")
  </code></pre>
