使用ant的Get任务也可以下载文件
Get getTask = new Get();
getTask.setProject(getProject());
getTask.setTaskName("bant.get");
getTask.setVerbose(this.verbose);
getTask.setDest(dest);
getTask.setSrc(remoteArtifact);
getTask.execute();

//还可以结合Mkdir任务建立目录
mkdirTask = new Mkdir();
mkdirTask.setProject(getProject());
mkdirTask.setTaskName("fetchTask.mkdir");
mkdirTask.setDir(destdir);
mkdirTask.execute();
