When I want to run the app, I get the following Build output:

Execution failed for task ':app:kaptGenerateStubsDebugKotlin'.
> Could not resolve all files for configuration ':app:kapt'.
   > Could not find com.android.databinding:compiler:4.2.1.

I searched it already up on stackoverflow but it didn't help. I am stuck on this issue for 2 days now and it's driving me nuts :/ My project build.gradle file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = "1.5.10"
    ext.version_navigation = "2.3.0"
    ext.version_core = "1.3.1"
    ext.version_constraint_layout = "2.0.0-rc1"
    ext.version_lifecycle_extensions = "2.2.0"
    ext.version_material = "1.2.0"

    repositories {

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"


        // Navigation
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$version_navigation"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}


allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }

I hope you can help me with that. Write me if you need more information on my project (e.g. fragment file or something like that).

CodePudding user response：

you dont need to put

kapt "com.android.databinding:compiler:4.2.1"

only need enable data binding in the gradle, and you did this
