Hi I am getting an error when I run the project, I have actually updated the gradle and gradle plugin versions and I am getting this error
can you please suggest what am I doing wrong here please
Task 'prepareKotlinBuildScriptModel' not found in project ':core'.
I added this to my gradle file already
tasks.register("prepareKotlinBuildScriptModel"){}
Added this to plugin section
id("com.android.application") version "7.1.1"
settings. gradle
pluginId.startsWith("com.android") -> useModule("com.android.tools.build:gradle:7.2.0")
project level build.gradle
buildscript {
val kotlinVersion by extra("1.5.21")
dependencies {
"classpath"("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")
classpath("com.android.tools.build:gradle:7.2.0")
one thing I noticed next to my build.gradle.kts - module version - Module: app-android-core.unitTest i don't see module version of the core any idea why that might have happened. this is whats in it
