Android(安卓)ANT 如何编译Jar 和 APK

最近在研究Android 的Ant 编译环境，遂将经验总结写下来。大家都知道我们可以在eclipse 里面编译android 的工程，这是怎么完成的呢？它主要是由于ADT 插件调用android的build tools完成的。其实eclipse 的编译也是通过Ant 脚本来完成编译的。/adnroid-sdk/tools/ant/build.xml 这就是ADT 插件调用的ant脚本，通过执行这个脚本就可以在完成android工程的编译。
那么如果不依赖ADT 插件，我们可以完成android 工程的编译呢？当然可以，首先必须安装Apache Ant，目前最新版本是1.9.4，下载解压放到android sdk 目录下，然后将其bin路径添加到环境变量PATH 。最后只需要在你的android 工程目录下编写build.xml 文件。
1. 如何编译Jar 文件，啥也不说了，直接上代码
下面为编译脚本build.sh 文件，最终会调用build.xml 文件。local.properties 文件是Ant 自动生成的，里面会自动指定 sdk.dir 变量，另外我们还手动指定了一个me.version,指定编译的版本号。
#!/bin/bashPROP_FILE=local.propertiesPROP_VERSION_KEY=me.versionVERSION=`cat ${PROP_FILE} | grep ${PROP_VERSION_KEY} | cut -d'=' -f2`GITSHA1=`git log | sed -n '1p' | awk '{print $2}'`MTL_OUTPUT=targetecho '##################################################### Android Build system####################################################'#预设置android sdk目录android update project -p .#1.编译jnindk-build cleanndk-build#2.编译jarant -f build.xmlecho '################################################### Make the tar package ##################################################'tar -cvf ${MTL_OUTPUT}/aliroot_${VERSION}_${GITSHA1}.tar.gz sdk
