flutter error: Execution failed for task ':flutter_inappwebview:compileDebugJavaWithJavac'

Question

when I am going to install my project in my mobile device then I got error to chenge compileSDKVersion 33.

After changing my compileSDKVersion 33 from compileSDKVersion 32, Then I got this error Execution failed for task ':flutter_inappwebview:compileDebugJavaWithJavac'.

This is my build.gradle file.

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.google.gms.google-services'

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    compileSdkVersion 33

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "org.mycwc"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    signingConfigs {
        release {

            storePassword keystoreProperties['storePassword']
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

Answer 2

Checkout your gradle plugin is compatible with your gradle version or not.

https://developer.android.com/studio/releases/gradle-plugin#updating-gradle

I have faced the same error when my gradle version was 6.7.1 while my plugin was 4.1.0. Updating the plugin to 4.2.0 solved it for me.

The gradle plugin version is located on android/build.gradle as classpath 'com.android.tools.build:gradle:{your version}' on the dependencies.

The gradle version is located on android/gradle/wrapper/gradle-wrapper.properties under distributionUrl.

Hopes it will help you.
