Android Studio : How to remove/filter build variants for default debug and release buildTypes and keep only those using custom buildTypes?

Question

I have created custom buildTypes as follows:

 buildTypes {
        releasefree.initWith(buildTypes.release)
        releasefree {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        releasepro.initWith(buildTypes.release)
        releasepro {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            applicationIdSuffix ".pro"
        }
        debugfree.initWith(buildTypes.debug)
        debugfree {
            shrinkResources true
            applicationIdSuffix ".debug"
            debuggable true
        }
        debugpro.initWith(buildTypes.debug)
        debugpro {
            shrinkResources true
            applicationIdSuffix ".pro.debug"
            debuggable true
        }
    }

I am not going to use the default debug and release build types ever and want to remove them from the build variants list. I have more than a few flavors and the list of variants is too huge. Removing the variants with default debug and release types will help as I'm never going to use them.

I tried using variant filter as follows but it did not work

android.variantFilter { variant ->
    if(variant.buildType.name.endsWith('Release') || variant.buildType.name.endsWith('Debug')) {
        variant.setIgnore(true);
    }
}

Is there something wrong in the way I'm filtering the variants or is it just not possible to remove the variants with default debug and release build types.

Answer 1

Figured it out. It was a really silly mistake on my part. The above variant filter does work. The names are all lower case and the upper case in the strings i was comparing with were the culprit.

Changing to the following (making compare strings lower case) made it work as expected:

android.variantFilter { variant ->
    if(variant.buildType.name.endsWith('release') || variant.buildType.name.endsWith('debug')) {
        variant.setIgnore(true);
    }
}

or this

android.variantFilter { variant ->
    if(variant.buildType.name.equals('release') || variant.buildType.name.equals('debug')) {
        variant.setIgnore(true);
    }
}
