Compilation error due to mismatch between compileDebugJavaWithJavac and compileDebugKotlin about flutter_contacts HOT 15 CLOSED

Add below code in your project level build.gradle file. This worked for me. Also help me in other modules where same issue occurred.

rootProject.buildDir = '../build'
subprojects {
  afterEvaluate {
        if (project.plugins.hasPlugin("com.android.application")
                || project.plugins.hasPlugin("com.android.library")) {

            if (project.name == "flutter_contacts") {
                project.android.compileOptions {
                    sourceCompatibility = JavaVersion.VERSION_17
                    targetCompatibility = JavaVersion.VERSION_17
                }
            }
        }
    }
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

Yes, it fixes the issue and the app now compiles fine on Android. Thanks!

I have also tried to comment out compileOptions and kotlinOptions in the app/build.gradle, replacing them with the jvmToolchain, but the error is still the same:

    kotlin {
        jvmToolchain(17)
    }

    //compileOptions {
    //    sourceCompatibility JavaVersion.VERSION_17
    //    targetCompatibility JavaVersion.VERSION_17
    //}

    //kotlinOptions {
    //    jvmTarget = '17'
    //}

Having same issues.

'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.

Nothing at all?

from flutter_contacts.

I fixed this by adding:

    kotlin {
        jvmToolchain {
            languageVersion.set(JavaLanguageVersion.of(8))
        }
    }

to the build.gradle file. Please modify your build.gradle file as follows:

group 'co.quis.flutter_contacts'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.9.0'
    ext.kotlin_coroutines_version = '1.6.4'
    repositories {
        google()
        jcenter()

Is this the same as #158 ?

from flutter_contacts.

I have already provided the solution, you simply need to implement it.

Add the following lines to your android/build.gradle:

    kotlin {
        jvmToolchain {
            languageVersion.set(JavaLanguageVersion.of(8))
        }
    }

And yes, this is related to #147 and #158

And it still happens with version 1.1.8

from flutter_contacts.

OH cmon developer!!! we need real fix for this problem, can you please upgrade you package!!

Is there any negative effect on the project? I mean, is this affecting anything else in the project or breaking something?

Can you please simply update the build.gradle file with the changes I have shown? It really takes 30 seconds, and fixes the issue.

This is what worked for me:
#142 (comment)

from flutter_contacts.

Hi all - thanks for your patience and the recommended solutions.

This should be fixed in version 1.1.9. If it is not, please let me know, and reopen this conversation.
