[BUG] ANDROID : The error occurred due to a mismatch in JVM target versions: compileDebugJavaWithJavac is set to 1.8, while compileDebugKotlin is set to 17

[LazreqYa]

Steps to Reproduce

Switch to this version

`------------------------------------------------------------ Gradle 8.9

Build time: 2024-07-11 14:37:41 UTC Revision: d536ef36a19186ccc596d8817123e5445f30fef8

Kotlin: 1.9.23 Groovy: 3.0.21 Ant: Apache Ant(TM) version 1.10.13 compiled on January 4 2023 Launcher JVM: 22.0.1 (Oracle Corporation 22.0.1+8-16) Daemon JVM: /Library/Java/JavaVirtualMachines/jdk-22.jdk/Contents/Home (no JDK specified, using current Java home) OS: Mac OS X 14.6.1 aarch64`

using Android Studio Gradle JDK 17

Expected behaviour

Want to run my android app with flutter run after a long time. The package works perfectly on ios but on android i can't compile.

Actual behaviour

Actually every package are compiling but the google_api_header because of this :

* What went wrong:
Execution failed for task ':google_api_headers:compileDebugKotlin'.
> Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17).

I got the same issue early this week on upgrading my app.

Found the solution by managing the upgrade of the Gradle and force the plugins to use the 17 version

Try:

Upgrade to gradle 8 distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-all.zip

Update the android application id "com.android.application" version '8.1.4' apply false

In your android build.gradle to adapt subprojects:

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    afterEvaluate {
        // check if android block is available
        if (it.hasProperty('android')) {
            if (it.android.namespace == null) {
                def manifest = new XmlSlurper().parse(file(it.android.sourceSets.main.manifest.srcFile))
                def packageName = manifest.@package.text()
                println("Setting ${packageName} as android namespace")
                android.namespace = packageName
            }
            def javaVersion = JavaVersion.VERSION_17
            android {
                def androidApiVersion = 34
                compileSdkVersion androidApiVersion
                defaultConfig {
                    targetSdkVersion androidApiVersion
                }
                compileOptions {
                    sourceCompatibility javaVersion
                    targetCompatibility javaVersion
                }
                tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
                    kotlinOptions {
                        jvmTarget = javaVersion.toString()
                    }
                }
                println("Setting java version to ${javaVersion.toString()} which is $javaVersion")
                println("Setting compileSdkVersion and targetSdkVersion to $androidApiVersion")
            }
        }

    }

}

@stact thanks for the answer i just try your solution but the new XmlSlurper() is not reconize, even if i add the import groovy.util.XmlSlurper.

i finally just downgrade the google_api_headers and stop using the flutter_google_place.
