環境：

1，OS：Windows7

2，JDK：jdk1.7

3，Apache Ant：apache-ant-1.9.6

步驟：

1，解壓apache-ant-1.9.6-bin.zip

2，新增環境變數ANT_HOME，比如C:\apache-ant-1.9.6-bin

3，Path變數新增ant的bin目錄，比如%ANT_HOME%\bin

目標流程：

1，刪除web project web-info目錄下的classes目錄；刪除.war檔案

2，建立web project web-info目錄下的classes目錄

3，複製src下的非java檔案

4，編譯生成java的class檔案

5，打包成.war檔案

Ant build.xml檔案
