Hi
I would like to know if anyone has managed to get arrow optics to work (e.g. generate code) in an Android studio project?
i have been trying to achieve this for the last 4 days and failed.

[Tower Guidev2]

my andriod studio version is

Android Studio Bumblebee | 2021.1.1

my project gradle is

buildscript {
    ext.kotlin_version = "1.6.10"
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.dagger:hilt-android-gradle-plugin:2.40.5'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
        maven { url '<https://jitpack.io>' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

and my android sub module gradle file (snippets)

plugins {
    id "com.android.library"
    id "com.google.devtools.ksp" version "1.6.10-1.0.2"
    id "kotlin-android"
    id "kotlin-kapt"
    id 'org.jetbrains.kotlin.plugin.serialization' version '1.4.20'
    id 'dagger.hilt.android.plugin'
}

android {
    compileSdkVersion 32

    defaultConfig {
        minSdkVersion 26
        targetSdkVersion 32

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles "<http://consumer-rules.pro|consumer-rules.pro>"
    }

compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }
    kotlinOptions {
        jvmTarget = '11'
        freeCompilerArgs += [
                "-Xopt-in=kotlinx.serialization.ExperimentalSerializationApi",
                "-Xopt-in=kotlinx.coroutines.ExperimentalCoroutinesApi",

    }
}

dependencies {

    api(platform("io.arrow-kt:arrow-stack:1.0.6-alpha.1"))
    api("io.arrow-kt:arrow-core")
    api("io.arrow-kt:arrow-fx-coroutines")
    api("io.arrow-kt:arrow-fx-stm")
    api("io.arrow-kt:arrow-optics")

    api "com.google.devtools.ksp:symbol-processing-api:1.6.10-1.0.2"
    ksp "io.arrow-kt:arrow-optics-ksp-plugin:1.0.6-alpha.1"

[Tower Guidev2]

the code i am using to test optics code generation is directly from tht optics docs as shown here

@optics
data class Street(val number: Int, val name: String) {
    companion object
}

@optics
data class Address(val city: String, val street: Street) {
    companion object
}

@optics
data class Company(val name: String, val address: Address) {
    companion object
}

@optics
data class Employee(val name: String, val company: Company?) {
    companion object
}

[Tower Guidev2]

what am i doing wrong? or missing?

[Tower Guidev2]

I found that by downgrading my sub module gradle arrow deps to these shown below the generation works for optics in android

implementation(platform("io.arrow-kt:arrow-stack:1.0.3-alpha.1"))
api("io.arrow-kt:arrow-core")
api("io.arrow-kt:arrow-fx-coroutines")
api("io.arrow-kt:arrow-fx-stm")
ksp 'io.arrow-kt:arrow-optics:1.0.3-alpha.1'
api 'io.arrow-kt:arrow-optics'

api "com.google.devtools.ksp:symbol-processing-api:1.6.10-1.0.2"
ksp "io.arrow-kt:arrow-optics-ksp-plugin:1.0.3-alpha.1"

I’ve been investigating and came to the same conclusion, the problem was in the version

[Alejandro Serrano Mena]

arrow-optics-ksp-plugin:1.0.3-alpha.2 would work too

[Alejandro Serrano Mena]

we need to fix our publishing pipeline because wrong artifacts like 1.0.6 have been published 😕

[Tower Guidev2]

thanks for the insight, i will give 1.0.3-alpha.2 a "run out" 😄
arrow is worth the effort 😉
