Can you try to cd android && ./gradlew --stop and try again?

[recepaltas]

Yes I tried many times . I created fresh app with npx create-react-native-app and enabled minifyEnabled = true . But didnt work. Same error did it. What is the problem i cant figure it out.

[cortinico]

Can you try to rm ~/.gradle and build again?

[recepaltas]

yes I tried many times. Same.

[recepaltas]

The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build.
This might happen in subprojects that apply the Kotlin plugins with the Gradle 'plugins { ... }' DSL if they specify explicit versions, even if the versions are equal.
Please add the Kotlin plugin to the common parent project or the root project, then remove the versions in the subprojects.
If the parent project does not need the plugin, add 'apply false' to the plugin line.
See: https://docs.gradle.org/current/userguide/plugins.html#sec:subprojects_plugins_dsl
The Kotlin plugin was loaded in the following projects: ':expo', ':expo-modules-core'

I think the main reason is this? How can I solve this?

When I create the project

• npx react-native@latest init Project --> minifyEnabled = true. -> No Problem
• npx create-react-native-app -> Blank Temlate -> minifyEnabled = true -> Error Same
  It has same error also npx react-native@latest init Project -> yarn add expo-core-modules -> Same Error

The Problem is multiple kotlin. There are different packages with kotlin plugins like expo,expo-module,react-native-screens,react-native-gestlure-handler etc.. How can I solve this?

[huan415201]

Does anyone solve this? I've tried gradlew clean, gradlew --stop, add to android/build.gradle org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m, but nothing fix this bug.

Can you create a small reproducer usign this template? https://github.com/react-native-community/reproducer-react-native

Then this is not a problem with React Native core but with either:

1. create-react-native-app -> should be reported here https://github.com/expo/create-react-native-app/issues
2. Expo Core Modules -> should be reported here https://github.com/expo/expo/issues

add this in your android/build.gradle
(this is for latest RN version 0.72.6)

buildscript {
    ext {
        ...
        kotlinVersion = findProperty('android.kotlinVersion') ?: '1.8.10'
    }
    dependencies {
        ...
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}")
    }

my another project kotlinVersion is 1.6.10 for RN 0.71.4
