常用配置

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

常用命令

gradle -q quite模式，出错才输出

gradle tasks --all 列出所有任务

gradle projects 列出当前目录下所以项目

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 ， 参考

settings.gradle

include ':pcgCommon', ':Juchaozhi'

local.properties ,用于配置sdk.dir

sdk.dir=/Volumes/DATA/tools/android-sdk-macosx

root项目下有两个项目 pcgCommon和Juchaozhi
root 项目build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

pcgCommon build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'
    }
}

apply plugin: 'android-library'


android {

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
  

• 检查的时候有问题也跳过
  lintOptions {
  abortOnError false
  }
  

• runProguard true 代码混淆的选项  参考
  

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

• 版本信息用正则匹配 AndroidManifest?.xml 这个文件
  

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

• 只编译release 可以采用 gradle assembleRelease
