Template plugin instead of "apply from"

Help/Discuss

I have a project with multiple modules, some are android libraries some are android apps, i see a lot of code in the build.gradle file is duplicated, especially for example the release part and key configuration is always the same.

One strategy is to include always a file like “apply from: releases.gradle” on every single module, but i think its a bit ugly especially because i need to write relative paths like “…/…/buildFiles/release.gradle”

Is there any better approach for this? Can i create a plugin that will insert basic releases inside the Android Block? If so, is there an example on how to do that? So a plugin that will generate this:

android {
    buildTypes {
        release {
            // Will not remove unused resources by default
            shrinkResources false
            // Run proguard
            minifyEnabled true
            proguardFile getDefaultProguardFile('proguard-android.txt')
            proguardFile '../assets/build/proguard-project.txt'
            // Sign
            signingConfig signingConfigs.release
            // Fallback for tasks
            matchingFallbacks = ['release']
        }
        // Public, Signed, Beta
        beta.initWith(buildTypes.release)
        beta {
            versionNameSuffix "beta"
            // Fallback for tasks
            matchingFallbacks = ['beta', 'release']
        }
        // Internal Release
        debug {
            versionNameSuffix "dbg"
            signingConfig signingConfigs.debug
            // Fallback for tasks
            matchingFallbacks = ['debug', 'beta', 'release']
        }
    }
}
