How to config hotfix use Nuwa?

1  Root Program
build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0-rc1'
        classpath 'cn.jiajixin.nuwa:gradle:1.2.2'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }
}

allprojects {
    repositories {
        jcenter()
    }
}

2  module   build.gradle

add  apply plugin: "cn.jiajixin.nuwa"

apply plugin: 'com.android.application'apply plugin: "cn.jiajixin.nuwa"

and

dependencies:

dependencies {

    compile 'cn.jiajixin.nuwa:nuwa:1.0.0'

}

Now  I meet this question:

原来是 gradle 版本不支持的原因：

如果用此版本，会报错Error:Cannot get property 'taskDependencies' on null object，乖乖降低到1.2.3，木有此问题

如果，这里的版本修改了话， 对应的这里的版本也要修改：

之前用的是 2.10  改成 2.2

有问题的版本

classpath 'com.android.tools.build:gradle:2.1.0-rc1' 

classpath 'com.android.tools.build:gradle:1.5.0' 

You can see the detail:  how to resolve it?

这个地方要

download the new gradlew version

So it is maybe so slow!

ProGuard

-keep class cn.jiajixin.nuwa.** { *; }

Now  we can  change the code and build the apk:

How to use Nuwa:

1  设置配置信息

   初始化 和 加载路径

 */public class HadesApplication extends Application{


    @Override    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);        Nuwa.init(this);        Nuwa.loadPatch(this,"/sdcard/patch.jar");    }


}

2  运行APK 会在 app/build/output/目录下面自动生成  nuwa 的目录

 将这个目录copy  到 一个指定的目录；

    Documents/Code/nuwa

3  修改你的代码 或者 你的bug  然后执行下面的命令

 ./gradlew clean nuwaDebugPatch -P NuwaDir=/Users/Hades/Documents/Code/nuwa

然后会在  app/build/output/nuwa/debug/目录下面生成 patch.jar  文件

这就是我们的补丁文件，

 这个时候我遇到一个问题：

可是 我明明已经定义了呀：
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:nuwaDebugPatch'.
> $ANDROID_HOME is not defined

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED
