1.bulid.xml的配置

2.java代码操作
import java.io.File;import org.apache.tools.ant.BuildException;import org.apache.tools.ant.Project;import org.apache.tools.ant.ProjectHelper;public class AntOperattion { public static void operateAnt(String buildPath,String targetName,String dyPath,String version){  String xmlPath = buildPath + "allDeployJsp//build.xml";        File buildFile = new File(xmlPath);                   Project p = new Project();           try {               p.fireBuildStarted();               p.init();               ProjectHelper helper = ProjectHelper.getProjectHelper();               helper.parse(p, buildFile);               p.setNewProperty("dyDir", dyPath);            p.setNewProperty("version", version);            p.executeTarget(targetName);            p.fireBuildFinished(null);           } catch (BuildException e) {               p.fireBuildFinished(e);           }       }   }
