"androidx dependency" is compiled by a new Kotlin compiler backend and cannot be loaded by the old compiler about compose-multiplatform

[veyndan]

I'm facing the same issue as @ggoraa, and my settings.gradle.kts is identical to that found in the Getting Started guide:

pluginManagement {
    repositories {
        gradlePluginPortal()
        maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
    }
}

We had similar problem earlier:
#21

And fixed it with #30

(we moved buildscript from settings.gradle.kts to the root build.gradle.kts and the problem was gone)

Do you have buildscript in settings.gradle.kts?

[Animeshz]

Same issue :(

Can you tell which versions of IDEA and Kotlin IDEA plugin do you use?

If it is possible it would be very helpful if you attach project archive here.

[Animeshz]

Intellij IDEA: 2020.2
Kotlin (plugin): 1.4.10
JB Compose: 0.1.0-m1-build62
JDK Version: 11.0.8
JVM Target: 1.8

[subashz]

Same issue.
It happens after creating multiplatform projects from intellij.
Intellij IDEA: 2020.3 EAP
Runtime version: 11.0.8
VM: Open JDK [64bit]

Repro: https://gofile.io/d/WpJQbh

Intellij IDEA: 2020.2
Kotlin (plugin): 1.4.10
JB Compose: 0.1.0-m1-build62
JDK Version: 11.0.8
JVM Target: 1.8

Unfortunately I can't reproduce the issue on this configuration.
I tried to open these templates:
https://github.com/JetBrains/compose-jb/tree/master/templates/desktop-template (which is almost the same as described in https://github.com/JetBrains/compose-jb/tree/master/tutorials/Getting_Started)
https://github.com/JetBrains/compose-jb/tree/master/templates/multiplatform-template

Can anyone that have this issue attach archive with project?

Also is there "-Xuse-ir" in Project Settings?

It should be added automatically after the import of the project.
If not - will it be added after Gradle Sync?

Strange enough, The same thing happens with the desktop-template project as well when (importing in Intellij).

[subashz]

I don't have any issue with desktop-template based project. It only happens on MPP template for me.

Multiplatform template from IDEA Wizard currently have this problem (we fixed it in a new version)

Try this:
demo.zip

I changed version to "0.1.0-m1-build62" and converted desktop module from kotlin("jvm") to kotlin("multiplatform")
(kotlin("jvm") doesn't work well in multiplatform project)

[subashz]

Got new error after tyring to run desktop app,

But it works fine if I replace

import me.subash.common.App
import androidx.compose.desktop.Window

fun main() = Window {
    App()
}

with

import androidx.compose.desktop.Window
import androidx.compose.material.Text

fun main() = Window {
    Text("Hello")
}

I forgot to change version in android/build.gradle.kts and common/build.gradle.kts

(you can redownload demo from a comment above, I changed the version)

[ggoraa]

Do you have buildscript in settings.gradle.kts?

I have just copy pasted all code from your getting started guide, and the IDEA just gone wild with errors.

EDIT: I moved pluginManagement part to build.gradle.kts, aaand... Everything just broke. Maybe I misunderstood you :D

Forgot to say, I have the Kotlin/JVM project, not the MPP one

EDIT: Also forgot to say:

Kotlin plugin: 1.4.10
JVM target: 11
JDK: OpenJDK14
IDEA: Latest stable

Easily. https://drive.google.com/file/d/1VRKk64t8z7GwYD6H2bp1hoF6z7nzYqFq/view?usp=sharing

[olonho]

What exactly version of IDEA? 2020.2.3?

[X1nto]

This is what I did to fix the problem: Went into project structure, I had "Use project settings" ticked so I clicked on "Edit project settings" and changed Target JVM Version to 11, then added -Xuse-ir to the command line options, after these operations red lines were gone. Screenshot of my project settings:

EDIT: I'm using 0.1.0-build113 btw

[ggoraa]

What exactly version of IDEA? 2020.2.3?

yes

[ggoraa]

I upgraded to the latest build of JetBrains Compose plugin, added the command line argument, and it is finally working! No more red lines :D

I changed the Gradle version from 6.3 to 6.5.1 and red underlining is gone.
On Gradle 6.7 and Compose 0.1.0-build113 everything is fine too.

[ggoraa]

I will try this too

[ggoraa]

I also forgot that my target JVM version was 1.6, after the upgrade to 11 every single error is gone

[igordmn]

It seems that everything is ok on the latest Gradle (6.7.1), Compose (0.2.0-build129), Kotlin (1.4.20) and Idea (2020.2.3).

We shouldn't manually add "-Xuse-ir" in project settings. It should be added automatically after Gradle Sync.

So if no one encounters this issue again I think we can close it.

Also if it still an issue, maybe similar changes will help:
https://github.com/JetBrains/compose-jb/pull/30/files

[steklopod]

My solution:
build.gradle.kts

plugins {
    val kotlin = "1.5.0-M1"
    kotlin("jvm") version kotlin
}
tasks{
            val java: String by project
            withType<KotlinCompile> {
                kotlinOptions { freeCompilerArgs += listOf("-Xskip-prerelease-check", "-Xjsr305=strict"); jvmTarget = java }; sourceCompatibility = java; targetCompatibility = java
            }
}
