在eclipse里，直接运行run as ant build就可以，生成build和dist文件夹:

 

 

Buildfile: D:\workspace_myprj_3.2\myprj\myprj-build-default.xml
clean-dist:
prepare:
    [mkdir] Created dir: D:\workspace_myprj_3.2\myprj\build
    [mkdir] Created dir: D:\workspace_myprj_3.2\myprj\dist
compile:
    [mkdir] Created dir: D:\workspace_myprj_3.2\myprj\build\WEB-INF\classes
     [copy] Copying 4317 files to D:\workspace_myprj_3.2\myprj\build
war:
      [war] Building war: D:\workspace_myprj_3.2\myprj\dist\myprj.war
      [war] Warning: selected war files include a WEB-INF/web.xml which will be ignored (please use webxml attribute to war task)
