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

All of them match the consumer attributes:
- Configuration 'debugApiElements':
- Found com.android.build.api.attributes.BuildTypeAttr 'debug' but wasn't required.

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{
}
}
