K/N android/ios kapt at intellij generated project

[MitsuraIvan]

Hi, at intellij generated project there is 1 build.gradle file for all platforms and because of kotlin-multiplatform plugin we cant use plugin kotlin-android and because of that kotlin-kapt plugin dont do anything. with kotlin-android plugin we got error Cannot add extension with name 'kotlin', as there is an extension already registered with that name. without kotlin-android plugin we got error Could not find method kapt() for arguments [android.arch.persistence.room:compiler:1.1.1] on object of type org.jetbrains.kotlin.gradle.plugin.mpp.DefaultKotlinDependencyHandler. it makes dagger/room and other stuff on android impossible to use which kinda kills the point of development. Any suggestions? is this a bug or bad gradle file?

project level build.gradle

buildscript { ext.kotlin_version = '1.3.0' repositories { google() jcenter() maven { url 'https://maven.google.com' } maven { url 'https://maven.fabric.io/public' } } dependencies { classpath 'com.android.tools.build:gradle:3.2.1' } } repositories { google() jcenter() }

app build.gradle

buildscript { repositories { google() jcenter() maven { url 'https://maven.google.com' } maven { url "https://plugins.gradle.org/m2/" } repositories { maven { url 'https://maven.fabric.io/public' } } }

@MitsuraIvan any solution found? I'm having the same issue :(

@4face-studi0 no from my side, sadly. You can try kotlin/native channel at slack, this thread got ignored, seems like it will not be possible with new project structure that using combined gradle for all platforms

@MitsuraIvan @4face-studi0 Kapt should work in multiplatform projects where an Android target is declared. First, note that kapt dependencies should be added after the Android target is declared in the kotlin { ... } block. You can move those dependency declarations below the kotlin { ... } block.

You don't need to apply the kotlin-android plugin in a project where kotlin-mulatiplatform is applied, the Android target that is declared in the kotlin { ... } scope should be enough.

If you face any further issues once you fix the kapt dependency declaration, feel free to comment here so I can look into it.
