Hey there, let's work through these build issues step by step. I'll show you exactly what changes to make in your Gradle files to get everything working smoothly.

1. Fix the Kotlin Gradle Plugin Version Error #

Your Android Gradle Plugin (AGP) 3.3.1 requires the Kotlin Gradle Plugin to be at least 1.3.0, but you're using 1.0.6. Here's how to update it:

Modify your root build.gradle file:
Change the kotlin_version to a compatible version (1.3.72 works perfectly with AGP 3.3.1):

buildscript {
    ext.kotlin_version = '1.3.72' // Updated from 1.0.6
    repositories {
        jcenter()
        maven { url 'https://maven.google.com/' name 'Google' }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

2. Resolve Deprecated Configuration Warnings #

The old dependency configurations are no longer supported—replace them with the modern equivalents:

• compile → implementation (for dependencies only used internally by your app)
• testCompile → testImplementation
• androidTestCompile → androidTestImplementation

3. Fix Build Tools Version Warning #

AGP 3.3.1 requires a minimum Build Tools version of 28.0.3. You have two simple options:

• Either explicitly set buildToolsVersion "28.0.3"
• Or remove the buildToolsVersion line entirely (AGP will automatically pick the correct version matching your compileSdkVersion)

I also recommend updating compileSdkVersion and targetSdkVersion to 28 to align with the Build Tools version—this avoids compatibility gaps.

Modified android-app Module build.gradle #

Here's the full updated file with all fixes applied:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28 // Updated from 26
    // Removed buildToolsVersion - AGP auto-selects the right version
    defaultConfig {
        applicationId "fr.curie.jonquille.jonquille_curie"
        minSdkVersion 18
        targetSdkVersion 28 // Updated from 26
        versionCode 203000

    }

    }
    dexOptions {
        javaMaxHeapSize "4g"
    }
}

Quick Notes #

• I updated support library and Google Play Services versions to match compileSdkVersion 28—this prevents version mismatch errors.
• Switched constraint-layout from a beta to a stable version for better reliability.

After making these changes, sync your Gradle project and it should build without errors or warnings!
