I’m following this guide to add compose to my existing app.. It says Make sure you're using Kotlin 1.5.21 in your project. Will Kotlin version 1.5.31 work?

[mkrussel]

I believe the latest version of compose wants 1.5.30.

You can disable the check, and it works with 1.5.31

[mkrussel]

This is what I did

@mkrussel thanks the guides tells me to do

plugins {
    id 'org.jetbrains.kotlin:android' version '1.5.21'
}

[Alexander Suraphel]

I didn’t have this on my existing app. is it a new thing?

[mkrussel]

It's another way of doing the plugin. I do it like

plugins {
    id("com.android.application")
    id("kotlin-android")
}

[Alexander Suraphel]

I only had:

[mkrussel]

But I'm using the Kotlin DSL for gradle and that sample is Groovy, but you need to make sure you are using an android plugin and the kotlin android plugin, which I'm guessing your app already is doing

[Alexander Suraphel]

implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"

[mkrussel]

You must be applying plugins in some manner or it wouldn't know how to build an android app.

[Alexander Suraphel]

I’m using the groovy DSL has been > 1 year since I set up the ap

[Alexander Suraphel]

my plugins are mostly implementation

[mkrussel]

Those are dependencies not plugins.

[Alexander Suraphel]

Hmm where do I put the plugin?

[Alexander Suraphel]

build.gradle? right

[mkrussel]

yes, and I'm sure you have them or else your would not be building an app

[mkrussel]

https://docs.gradle.org/current/userguide/plugins.html

[Alexander Suraphel]

@mkrussel i think this was what I had:
apply plugin: 'kotlin-android'

[Albert Chang]

Do not suppress Kotlin version check unless you really know what you are doing. I don't think Compose 1.0.1 is compatible with Kotlin 1.5.31. It's just that the versions in the tutorial aren't latest. The latest stable version 1.0.3 supports Kotlin 1.5.31. You can check the latest version here.

[Alexander Suraphel]

Is

plugins {
    id 'org.jetbrains.kotlin:android' version "$kotlin_version"
}

alternative syntax for:

apply plugin: 'kotlin-android'

?

[mkrussel]

I believe so

[mkrussel]

@Albert Chang The latest version compose 1.0.3 officially only supports Kotlin 1.5.30, but it does work with Kotlin 1.5.31. I agree disabling the version check is very risky, which is why I replaced it with my own version check in the gradle script.

[Alexander Suraphel]

Getting this @mkrussel am I missing something?

[mkrussel]

Line 6 is already applying the plugin, so just remove the plugin block.

[Alexander Suraphel]

I tried removing line 6 with the same error…

[mkrussel]

Keep line 6 and remove the plugin portion that is complaining. It is not needed because you have line 6.
