<script language="javascript"><![CDATA[
         var version = java.lang.System.getProperty("java.version");
         if ( version.startsWith("1.8.0")) {
             load(Packages.org.apache.tools.ant.types.ZipFileSet);
             load(Packages.org.apache.tools.ant.taskdefs.Zip);
         } else {
             importClass(Packages.org.apache.tools.ant.types.ZipFileSet);
             importClass(Packages.org.apache.tools.ant.taskdefs.Zip);
