How to apply plugin to only one flavor in gradle?

Question

I have a multi-flavored, multi-build-typed android project and I want to integrate the NewRelic plugin. But I have to apply it only for one of the customers, thus only for one product flavor.
NewRelic uses instrumentation and the plugin would generate code in other flavors if I applied the plugin there, and that is not permitted for us.

So my question is: How can I use the apply plugin: something command in the gradle file to be applied to only one of my flavors?

Answer 1

Use this code:

if (!getGradle().getStartParameter().getTaskRequests()
        .toString().contains("Develop")){
    apply plugin: 'com.google.gms.google-services'
}

getGradle().getStartParameter().getTaskRequests().toString() returns something like [DefaultTaskExecutionRequest{args=[:app:generateDevelopDebugSources],projectPath='null'}] so as stated in the comments Develop must start with an uppercase.

1. Define variable - def fl

2. Initialize variable in you Flavours (and/or builds)

       productFlavors {
   
               freeFlavour {
                   (...)
                   fl = "free"
               }
   
               paidFlavour {
                   (...)
                   fl = "paid"
               }
           }
   

3. Use if statement -

   if (fl == "free") { apply plugin: something }

I found a solution, but it is not the best so far. So I'm not sure anymore, that what I wanted to do initially is possible. The gradle file evaluation and the choosing of the right flavor and build type is in different phases of the gradle build, so what I've done is:

I use a build parameter from the command line. When that paramerer is true, I apply the plugin, when it is not even there, I also apply it (for IDE build). I use Jenkins, so I could write that parameter in the build job.

build.gradle file:

// First we have to attach a task to the project, which will be running first
gradle.projectsEvaluated {
    preBuild.dependsOn(applyNewRelicByProperty)
}

// Then check on the parameter, which comes from the command line
task applyNewRelicByProperty {
    if(!project.hasProperty('compileNewRelic')) {
        // NewRelic on: 'compileNewRelic' property not set, so running from IDE.
        apply plugin: 'newrelic'
    } else if(project.hasProperty('compileNewRelic') && project.getProperties().get('compileNewRelic').equals('true')) {
        // NewRelic on: 'compileNewRelic' property is set and it is 'true'.
        apply plugin: 'newrelic'
    } else {
        // NewRelic off
        println("No NewRelic")
    }
}

And you have to run the gradle build by this:

assembleYourApp -PcompileNewRelic=true

Tried different solutions, but none of them worked for me. This is what I came up with and seems to work as far as I tested:

build.gradle

productFlavors {
    someFlavorWithGoogleGcm {
        dimension "type"
        applicationId "com.example.withGcm"
        ext.useGoogleGcm = true
    }
    someFlavorWithoutGoogleGcm {
        dimension "type"
        applicationId "com.example.withoutGcm"
    }
}

And outside the configuration, inside the build.gradle file:

android.productFlavors.each { flavor ->
    if (getGradle().getStartParameter().getTaskRequests().toString().toLowerCase().contains(flavor.name) && flavor.ext.useGoogleGcm) {
        println("Building flavor with Google GCM [${flavor.name}] - applying plugin")
        apply plugin: 'com.google.gms.google-services'
    }
}
