You need to download ant, proguard and configure them first.
Then you have to genarate a build.xml file use the following command:
$android update
project --path
path is the full path of your android project, eg:~/code/workspace/ENotes
now you can see there's a build.xml file under ~/code/workspace/ENotes.
Then you have to configure your build.xml file. Including sign, optimize, align.
Here's my example build.xml file.
1 <?xml version="1.0" encoding="UTF-8"?> 2 3 <project name="ENotes" default="help"> 4 5 6 7 <!-- The local.properties file is created and updated by the 'android' tool. 8 9 It contains the path to the SDK.

Then you can enter the project's directory and use command:
$ant release
to genarate a release version of result.
Some time there are mistakes like
[javac]****警告：编码 ascii 的不可映射字符********
出现“警告：编码 ascii 的不可映射字符”错误
To solve this kind of mistake, find the javac part in build.xml file, change the encoding 'ascii' to an appropriate one.
such as 'gbk' or 'utf-8'
