gradle中英文  http://gradle.org/ http://doc.gradle.cn/wiki/gradle-main?hl=main [[BR]]

项目转换为gradle  http://tools.android.com/tech-docs/new-build-system/intellij_to_gradle [[BR]]
gradle android 详细说明 http://tools.android.com/tech-docs/new-build-system/user-guide [[BR]]
多渠道打包  http://www.cnblogs.com/youxilua/archive/2013/05/20/3087935.html [[BR]]


== 常用配置 ==

 
apply plugin: 'java': 指定项目为java项目[[BR]]
apply plugin: 'android' 指定为android项目
apply plugin: 'android-library':增加android库项目[[BR]]


== 常用命令 ==

gradle -q quite模式，出错才输出[[BR]]

gradle tasks --all 列出所有任务[[BR]]

gradle projects 列出当前目录下所以项目[[BR]]

gradle :app:tasks   例如 gradle test:assemble  运行test项目assemble任务，相关前置任务会检查一次



== 例子 ==

以聚超值为例子，因为要多个项目构成，需要settings.gradle 这个文件 ，[http://www.cnblogs.com/CloudTeng/p/3418425.html 参考][[BR]]

settings.gradle
{{{
include ':pcgCommon', ':Juchaozhi'

local.properties ,用于配置sdk.dir

''注意事项''
* 要注意有些旧项目的AndroidManifest.xml不符合新的规范要加上     useOldManifestMerger true 这个参数 [[BR]]

* 检查的时候有问题也跳过 [[BR]] lintOptions {  [[BR]] abortOnError false   [[BR]]}  [[BR]]

* runProguard true 代码混淆的选项 [http://www.cnblogs.com/blfshiye/p/3796384.html 参考] [[BR]]

* 市场列表文件用Unix回车分割，用其他分割修改这里 split("\n")[[BR]]

* 版本信息用正则匹配 AndroidManifest.xml 这个文件 [[BR]]

* 市场替换的代码  line.replaceAll("MOFANG_CHANNEL_VALUE", "$market")，设置manifestFile文件 variant.processResources.manifestFile [[BR]]

* 只编译release 可以采用 gradle assembleRelease [[BR]]

* 调过lint[[BR]]   tasks.whenTaskAdded { task -> [[BR]] if (task.name.equals("lint")) { [[BR]]  task.enabled = false [[BR]]   } [[BR]] }[[BR]]


== lint 和  Proguard==

[http://proguard.sourceforge.net/ proguard官方说明] [[BR]]
打开注释 runProguard true ，修改proguard.txt可以打开混淆选项 [[BR]]
{{{
    buildTypes{
        release {
            signingConfig  signingConfigs.myConfig

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), "${rootDir}/proguard.txt"
        }
    }

sdk里面提供的proguard-android-optimize.txt大致为 [[BR]]
