"compileReleaseJavaWithJavac'" Error when trying to output application in AAB format in flutter

Question

I coded an application with Flutter, I want to get an output of the application in appbundle (aab) format. The 2 libraries I use cause the same error.

Execution failed for task ':agora_uikit:compileReleaseKotlin'.

Execution failed for task ':emoji_picker_flutter:compileReleaseKotlin'.

Both have the same description of the error message:

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

I checked my build.gradle file at project level and application level many times. I tried to solve the problem with ChatGPT for hours. The only suggestion he gave me was to change this part

compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }

    kotlinOptions {
        jvmTarget = '17'
    }

I tried many different variations like following:

JavaVersion.VERSION_17
jvmTarget = '17'

JavaVersion.VERSION_11
jvmTarget = '11'

JavaVersion.VERSION_1_8
jvmTarget = '1.8'

Btw, my kotlin version: 1.9.0

I am grateful in advance for any help.

I think this problem is caused by a bug. I found a workaround.

Add the following command to your gradle.porperties file.

kotlin.jvm.target.validation.mode = IGNORE
