Gradle configuration problem in 2.0.7

[bejibx]

Hi! I think I suddenly break gradle configuration with my recent PR with incap support.

For version 2.0.7 to work properly I have to add both paperparcel and paperparcel-api artifacts even despite the fact that paperparcel-api declared using api configuration inside paperparcel module.

Here is Android documentation about dependency configurations. So if add PaperParcel dependency like this:

implementation "nz.bradcampbell:paperparcel:2.0.7"
kapt "nz.bradcampbell:paperparcel-compiler:2.0.7"

I cant build my project because classes from paperparcel-api module are not visible in my project.

So to fix this I have to also declare dependency to paperparcel-api:

implementation "nz.bradcampbell:paperparcel:2.0.7"
implementation "nz.bradcampbell:paperparcel-api:2.0.7"
kapt "nz.bradcampbell:paperparcel-compiler:2.0.7"

Hmm, I wonder why. It looks like it is declared as an API dependency https://github.com/grandstaish/paperparcel/blob/master/paperparcel/build.gradle#L30

So I create sample project to check this is not some weird issue with my main project and still got same behavior. build.gradle file is pretty standard:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "ru.bejibx.koin"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.core:core-ktx:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'nz.bradcampbell:paperparcel:2.0.8'
    implementation 'nz.bradcampbell:paperparcel-kotlin:2.0.8' // Optional
    kapt 'nz.bradcampbell:paperparcel-compiler:2.0.8'
}

Again, I have to add implementation 'nz.bradcampbell:paperparcel-api:2.0.8' to be able to use @PaperParcel annotation and other classes from paperparcel-api module. Maybe we should update readme while we are trying to find out whats going on?

[bejibx]

Could this be related to how this library is packaged? Maybe we should update some gradle plugin to properly support new dependency configurations?

[bejibx]

Maybe this will be helpful? Or probably we should update android-maven-gradle-plugin?
