使用maven构建android项目

为什么引入maven构建方式

做过java后台开发的人员应该都知道,maven使用解决依赖包管理问题的,同时优化测试，打包，部署等流程的.

在android里,

maven可以管理你的依赖包

打包成apklib,管理自己的组件库

动态配置你的发布渠道(此点非常方便)

签名，打包，混淆一条龙服务.

开始使用maven

引入pom.xml

安装本地依赖包

由于国内的第三方库多未以maven形式打包,故我们要手动将jar包安装到本地maven库.（高德地图为例）

mvn install:install-file -DgroupId=com.autonavi -DartifactId=libamapv3 -Dversion=v3 -Dfile=/Users/keepcleargas/Downloads/AMapSDKV2Demo/libs/armeabi/libamapv3.so -Dpackaging=so -DgeneratePom=true -Dclassifier=armeabi

mvn install:install-file -DgroupId=com.autonavi -DartifactId=location -Dversion=2.0.0 -Dfile=/Users/keepcleargas/Downloads/AMapSDKV2Demo/libs/MapApiLocation.jar -Dpackaging=jar -DgeneratePom=true

添加依赖包到pom.xml

<dependency>
<groupId>com.autonavi</groupId>
<artifactId>libamapv3</artifactId>
<version>v3</version>
<classifier>armeabi</classifier>
<scope>runtime</scope>
<type>so</type>
</dependency>
<dependency>
<groupId>com.autonavi</groupId>
<artifactId>map</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>com.autonavi</groupId>
<artifactId>ApiLocation</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>com.autonavi</groupId>
<artifactId>ApiSearch</artifactId>
<version>2.0.0</version>
</dependency>

android的maven版本构建

由于在maven central中 android版本只有4.1.1.4

我们需要一个工具来安装新版的android sdk. Maven Android SDK Deployer.

根据Maven Android SDK Deployer的wiki 文案,

mvn
install -P 4.4

在pom.xml导入 4.4.2的安卓包.

<dependency>
<groupId>android</groupId>
<artifactId>android</artifactId>
<version>4.4.2_r3</version>
<scope>provided</scope>
</dependency>

构建中可能出现的问题

maven版本问题 使用过程中可能会出现版本问题,笔者这里用的是maven 3.1.1,

com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.8.2

.9图片问题

ERROR: 9-patch image Project/res/drawable-  hdpi/input_03_mid.9.png malformed.
[INFO]        Must have one-pixel frame that is either transparent or white.
[INFO] ERROR: Failure processing PNG image Project/res/drawable-hdpi/input_03_mid.9.png

将.9图片标准化 即可

命令执行

mvn clean package

打包，但不部署。
mvn clean install

打包，部署并运行。
mvn clean package android:redeploy android:run

这个命令通常用于手机上已经安装了要部署的应用，但签名不同，所以我们打包的同时使用redeploy命令将现有应用删除并重新部署，最后使用run命令运行应用。
mvn android:redeploy android:run

不打包，将已生成的包重新部署并运行。
mvn android:deploy android:run

部署并运行已生成的包，与redeploy不同的是，deploy不会删除已有部署和应用数据。

mvn clean install -Prelease,channel-91

打包签名,的渠道为channel-91的apk
