Fix build failure: Remove Kotlin 2.0+ compose-compiler plugin for 1.9.25 compatibility by Copilot · Pull Request #2 · ageon1156/Meshtastic-Android

Copilot · 2026-01-22T04:02:24Z

The build was attempting to use org.jetbrains.kotlin:compose-compiler-gradle-plugin which doesn't exist for Kotlin 1.9.x (introduced in 2.0+).

Changes

gradle/libs.versions.toml

Added compose-compiler = "1.5.14" (Kotlin 1.9.25 compatible version)
Commented out compose-gradlePlugin library and compose-compiler plugin references

build-logic/convention/build.gradle.kts

Removed compileOnly(libs.compose.gradlePlugin) dependency

build-logic/convention/src/main/kotlin/org/meshtastic/buildlogic/AndroidCompose.kt

Replaced Kotlin 2.0+ ComposeCompilerGradlePluginExtension configuration with legacy composeOptions:

commonExtension.composeOptions {
    kotlinCompilerExtensionVersion = libs.version("compose-compiler")
}

Removed compiler metrics/reports/stability configuration (unavailable in 1.9.x)

Convention plugins

Removed compose-compiler plugin application from AndroidApplicationComposeConventionPlugin, AndroidLibraryComposeConventionPlugin, and KmpLibraryComposeConventionPlugin

Trade-offs

Compose compiler metrics and reports are unavailable until Kotlin 2.0+ upgrade.

Original prompt

Problem

The build is failing with the following error:
Execution failed for task ':build-logic:convention:compileKotlin'.
> Could not resolve all files for configuration ':build-logic:convention:compileClasspath'.
   > Could not find org.jetbrains.kotlin:compose-compiler-gradle-plugin:1.9.25.
     Searched in the following locations:
       - https://plugins.gradle.org/m2/org/jetbrains/kotlin/compose-compiler-gradle-plugin/1.9.25/compose-compiler-gradle-plugin-1.9.25.pom
       - https://repo.maven.apache.org/maven2/org/jetbrains/kotlin/compose-compiler-gradle-plugin/1.9.25/compose-compiler-gradle-plugin-1.9.25.pom
       - https://jitpack.io/org/jetbrains/kotlin/compose-compiler-gradle-plugin/1.9.25/compose-compiler-gradle-plugin-1.9.25.pom
     Required by:
         project :build-logic:convention
Root Cause

The compose-compiler-gradle-plugin was introduced in Kotlin 2.0+ and does not exist for Kotlin 1.9.x versions. The current configuration in gradle/libs.versions.toml references:
compose-gradlePlugin = { module = "org.jetbrains.kotlin:compose-compiler-gradle-plugin", version.ref = "kotlin" }
Where kotlin = "1.9.25" - but this plugin doesn't exist for that version.

The dependency is used in build-logic/convention/build.gradle.kts on line 48:
compileOnly(libs.compose.gradlePlugin)
Required Changes
gradle/libs.versions.toml:

Add a separate compose-compiler version that is compatible with Kotlin 1.9.25 (use 1.5.14 which is the latest compatible version)

Remove or update the compose-gradlePlugin library reference since org.jetbrains.kotlin:compose-compiler-gradle-plugin doesn't exist for Kotlin 1.9.x

build-logic/convention/build.gradle.kts:

Remove the compileOnly(libs.compose.gradlePlugin) dependency on line 48 since this plugin doesn't exist for Kotlin 1.9.x
Update any Compose convention plugins (e.g., AndroidLibraryComposeConventionPlugin.kt, AndroidApplicationComposeConventionPlugin.kt) to use kotlinCompilerExtensionVersion instead of the Kotlin Compose plugin approach:
composeOptions {
    kotlinCompilerExtensionVersion = "1.5.14"
}
Remove the compose-compiler plugin reference from libs.versions.toml plugins section (line 206) if it causes issues:
# Remove: compose-compiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }
Compatibility Matrix

Component Version

Kotlin 1.9.25

Compose Compiler 1.5.14

AGP 8.1.2

Gradle 8.5

Verification

After the fix, running ./gradlew :build-logic:convention:compileKotlin should complete successfully without the "Could not find" error.
