如何在build.gradle中使用不同的依赖关系？

Question

(related to my question here )

I want to publish a one time update for my app for minSdk < 14 (compared to the current minSdk = 15. I am considering creating two flavors of my app - one that supports API levels lower than 14 with android support library 25.4.0 , and for API level 14 and newer that uses the latest support library 27.1.1, which only support API 14 and above.

Can the dependencies section of the build.gradle support different packages imports for different flavors?

My first try looks like this:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
    flavorDimensions "standard", "oldApi"

    defaultConfig {
        versionCode 37
        versionName "2.1.3"
        applicationId "org.app"
    }

    productFlavors {
        standard {
            dimension "standard"
            targetSdkVersion 27
            minSdkVersion 15
        }

        oldApi {
            dimension "oldApi"
            versionNameSuffix "X" //for old devices
            targetSdkVersion 14
            minSdkVersion 8
            maxSdkVersion 14
        }
    }

    signingConfigs {...}
    }

    buildTypes {
        release {...}
        debug {...}
    }
}

dependencies {
    standardImplementation project(path: ':MyappLibrary', configuration: 'standard')
    oldApiImplementation project(path: ':MyappLibrary', configuration: 'oldApi')
}

and:

apply plugin: 'com.android.library'
android {
    compileSdkVersion 27
    flavorDimensions "standard", "oldApi"

    productFlavors {
        standard {
            dimension "standard"
        }

        oldApi {
            dimension "oldApi"
        }
    }
}

dependencies {
    api 'com.dropbox.core:dropbox-core-sdk:3.0.6'
    standardApi "com.android.support:appcompat-v7:$package_version"
    standardApi "com.android.support:support-v4:$package_version"
    oldApiApi 'com.android.support:appcompat-v7:25.4.0'
}

Errors (note the bolded parts):

Unable to resolve dependency for ':app@ standardOldApiDebug /compileClasspath': Could not resolve project :MyappLibrary.

You can specify:

productFlavors {
        f1 {
           //..
        }
        f2 {
           //..
        }
   }

dependencies{         
    f1Implementation 'com.android.support:appcompat-v7:XX.2.1'
    f2Implementation 'com.android.support:appcompat-v7:27..1'
}
