android library增加productFlavors,并在app module 引用某个flavors

productFlavors{
buildConfigField "boolean", "ReadTestServer", "false"sdkDemoTest{
buildConfigField "boolean", "ReadTestServer", "true"
buildConfigField "boolean", "SDKDemo", "true"
}
sdkDemoOfficial{
buildConfigField "boolean", "SDKDemo", "true"
}
}

compile project(':app'） 会发现无法引用到项目，编译会发现library中的所有类都无法找到

需要使用如下方式指定使用的flavors进行引用：

compile project(path: ':app',configuration:'sdkDemoOfficialDebug')

或

compile project(path: ':app',configuration:'sdkDemoOfficialRelease')
