Android Studio3.0多渠道打包遇到的一个小问题

最近升级到了Android Studio3.0,在给测试打包的时候突然出错，错误如下：

Error:Cannot choose between the following configurations of project :UMUpdate:  
  - debugApiElements  
  - debugRuntimeElements  
  - releaseApiElements  
  - releaseRuntimeElements  
All of them match the consumer attributes:

查了以下，发现在3.0上打包的话，如果你的app moudle有几种buildTypes的话，所依赖的moudle也必须有几种（不做具体实现也可以），什么意思呢？ 比如，你的app目录下的build.gradle文件中，buildTypes如下：

buildTypes {
        release {
            buildConfigField "boolean", "LOG_DEBUG", "false"
            zipAlignEnabled true
            shrinkResources true
            minifyEnabled true
            proguardFiles 'proguard-rules.pro'
        }

        debug {
            buildConfigField "boolean", "LOG_DEBUG", "true"
            zipAlignEnabled true
            shrinkResources false
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

        debug2{

        }
    }

同时，你的app依赖一个第三方moudle比如叫UMUpdate，则在UMUpdate目录下的build.gradle文件中，也必须声明上边儿这三种buildTypes，当然，可以不做具体处理：

buildTypes {
        release {

        }

        debug {

        }

        debug2{

        }
    }
