How to access gradle defaultConfig in a parent gradle file

Question

I want to access the defaultConfig which define in a subproject (app--> build.gradle) into a parent build.gradle but seems to be not working OR I am doing something wrong. Actually I need to access the buildvarient which I define in a defaultConfig of app build.gralde file.

app build.gradle:

android {
    def buildTypeV // define here to update in loop

     dependencies.metaClass.allCompile { dependency ->
        buildTypes.each { buildType ->
      //      "${buildType.name}Compile" project(path: ":${dependency.name}", configuration: buildType.name)
            buildTypeV=buildType.name
        }
    }

    defaultConfig {
         versionNameSuffix "${buildTypeV}"
    }

From parent build.gradle file, I am doing like this to access versionNameSuffix:

gradle.buildFinished {

     def buildV=${project.android.defaultConfig.versionNameSuffix};
        println "buildV:::: $buildV"

    }

It seems to be a wrong way to access the defaultConfig as the build is failing it. Can someone give me an idea of how I can access It properly?

Error which I see on console:

* What went wrong:
Could not find method $() for arguments [build_8kbbn8x9zcumz6eqfx8ryt61s$_run_closure2$_closure3@77596dd9] on root project 'df-backpack' of type org.gradle.api.Project.

In my subproject define application variant:

android.applicationVariants.all { variant ->
    variant.outputs.all {
        def flavor = variant.name
        outputFileName = "../app-${flavor}-final.apk"
    }
    variant.assembleProvider.get().doLast getbuilder(variant.name.toLowerCase())
}

// in parent build.gradle:

 project('hpnurse') {
        buildStr=it. android.applicationVariants.all;
        //also tried like this 
        //it.variant.buildType.name;

    }

Please, post also the error you are getting. – Giorgio Antonioli Apr 06 '20 at 12:59 — Giorgio Antonioli, Apr 06 '20 at 12:59

When you are calling project.android you referring to the caller project, in your case, the parent project. Instead, you should refer to your Android subproject.

From the parent project you can access a specific subproject by name using project(name).

gradle.buildFinished {
    project('app') {
        def buildV = it.android.defaultConfig.versionNameSuffix
        println "buildV:::: $buildV"
    }
}

This seems to be working fine, Can I know it is possible to get the buildVariant of subproject in a parent in the same way? – user565 Apr 06 '20 at 16:33
@user565 you can get all the variants combining your build types and your flavors – Giorgio Antonioli Apr 06 '20 at 16:35
Sorry i am not getting this. Can you please show how I can access variant.name in parents project? I have updated my questions – user565 Apr 06 '20 at 16:38
@user565 To get the current variant you can do something like this: https://stackoverflow.com/a/34679933/4237609 – Giorgio Antonioli Apr 06 '20 at 16:40
Have no luck by using this. I have added getCurrentFlavor in parent build.gradle file and when try to access it it is showing empty value in response. – user565 Apr 06 '20 at 17:20
@user565 I never had the need to get the current variant so I don't have a ready answer honestly. Have you tried searching other answers on SO for that? – Giorgio Antonioli Apr 06 '20 at 17:21
Yes, try all others as well. – user565 Apr 06 '20 at 17:23
