环境：ibm rational software development platform
源码：
import java.io.File;
import org.apache.tools.ant.DefaultLogger;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.ProjectHelper;
public class anttest {

  public static void main(String[] args) {


    File buildFile = new File("build.xml");
    Project p = new Project();

    DefaultLogger consoleLogger = new DefaultLogger();
    consoleLogger.setErrorPrintStream(System.err);
    consoleLogger.setOutputPrintStream(System.out);
    consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
    p.addBuildListener(consoleLogger);

    p.init();
    ProjectHelper helper = ProjectHelper.getProjectHelper();
    helper.parse(p, buildFile);
    p.executeTarget(p.getDefaultTarget());
  }
}

怎么老是报如下错误：
