Why i am getting these errors while building gradle in android studio?


I am new into this and it is becoming a big mess for me. Please someone tell me how can i reduce these errors because my most of the time is wasted in solving these rather than learning android.

Do tell me if anything else is needed.

The error is like ------------>

*FAILURE: Build failed with an exception. What went wrong: java.lang.NoClassDefFoundError: org/jetbrains/kotlin/gradle/plugin/KotlinCompilerPluginSupportPlugin org/jetbrains/kotlin/gradle/plugin/KotlinCompilerPluginSupportPlugin My libs.version.toml file

Accepted Answer

its hard to debug from here. for me it seems your kotlin plugin is not applied.

My build.gradle(App level)

plugins {
    alias(libs.plugins.android.application)
    alias(libs.plugins.hilt)
    alias(libs.plugins.ksp)
    alias(libs.plugins.kotlin.android) // add this
}

My Project level gradle file

plugins {
    alias(libs.plugins.android.application) apply false
    alias(libs.plugins.hilt) apply false
    alias(libs.plugins.ksp) apply false
   alias(libs.plugins.kotlin.android) apply false // add this
}

you might have to stop your gradle deamons and restart your IDE. If that does not help refresh your dependencies (`.gradlew/ --refrehs-dependencies`).
