基本配置--build.properties
首先编写基本配置build.properties ，主要配置如下：
- android sdk所在目录
- 编译项目所使用的项目版本
- Jdk所在目录
- 以及签名时，所需要的密钥文件名称和密码等信息（keystore文件存在在主工程根目录下）
- 以下标红的信息请注意替换成自己的skd等所在目录。
sdk.home= E: \\android_env\\android-sdks-new
sdk.platform= android-15
jdk.home= D: \\Java\\jdk1.6.0_16
keystore.password= 123456
keystore.name= my.keystore
keystore.alias= read
项目配置--auto-build.properties：
- 主工程绝对路径
- lib库1的绝对路径
- lib库2的绝对路径
- 打包工程的绝对路径
因为这些都是绝对路径，所以大家在下载demo后，在eclipse中附加工程时，请注意勾选copy to workspace选项。防止出现找不到文件路径的问题。以下绝对路径也注意要修改成自己工作空间所在的绝对路径。
mainproject.abs= E:\\linshi-workspace\\testAutobuild
libproject.abs= E:\\linshi-workspace\\testLibOne
libproject2.abs= E:\\linshi-workspace\\testLibTwo
curproject.abs= E:\\linshi-workspace\\auto-builder
重要的是Ant构建脚本

注意事项：脚本中配置了项目的名称，注意可以改成自己的项目名称
两个lib库的包名，可根据自己需要增加或者删除
两个lib库的包名，可根据自己需要增加或者删除
省去若干调试，查询资料过程若干……终于跑通了
这样，我们的自动打包就算初具雏形，跑一下ant脚本，就可以将包自动打出来。
