使用Jenkins进行android项目的自动构建（2）
Maven and POM
1. 什么是Maven？
官方的解释是： http://maven.apache.org/guides/getting-started/index.html#What_is_Maven
2. 什么是POM
官方的解释是： http://maven.apache.org/pom.html#What_is_the_POM
3. POM的具体例子

例子中各个plugin的版本互相有依赖关系的，如果换了其他版本，有可能导致失败。有时在运行测试的过程会提示java.lang.RuntimeException: Stub! at junit.framework.Assert.assertEquals(Assert.java:30)，可以尝试调整dependencies中的依赖顺序来解决问题。
最后打包出来的apk，可以用aapt dump badging APK文件名来查看包信息，解压出CERT.RSA，用keytool -printcert -file CERT.RSA 命令来查看签名的MD5、SHA1、SHA256值及签名算法。
