I’m building a movies app and trying to import some online libraries. However, when I try to use them in another file, it shows “unresolved reference.” I’ve tried everything to fix it but there’s still no change. I followed each and every step given by ChatGPT and also from similar questions asked here.

Libraries I’m using:
File name: libs.versions.toml

[versions]
appcompat = "1.7.0"
material = "1.12.0"
activity = "1.9.0"
constraintlayout = "2.1.4"
glide = "4.12.0"
gson = "2.10.1"
volley = "1.2.1"
junit = "4.13.2"
extjunit = "1.1.3"
espresso = "3.4.0"

[libraries]
appcompat = { group = "androidx.appcompat", name = "appcompat", version.ref = "appcompat" }
material = { group = "com.google.android.material", name = "material", version.ref = "material" }
activity = { group = "androidx.activity", name = "activity", version.ref = "activity" }
constraintlayout = { group = "androidx.constraintlayout", name = "constraintlayout", version.ref = "constraintlayout" }
glide = { group = "com.github.bumptech.glide", name = "glide", version.ref = "glide" }
gson = { group = "com.google.code.gson", name = "gson", version.ref = "gson" }
volley = { group = "com.android.volley", name = "volley", version.ref = "volley" }
junit = { group = "junit", name = "junit", version.ref = "junit" }
ext.junit = { group = "androidx.test.ext", name = "junit", version.ref = "extjunit" }
espresso.core = { group = "androidx.test.espresso", name = "espresso-core", version.ref = "espresso" }

settings file to use the lib file
File name: settings.gradle.kts

pluginManagement {
    repositories {
        google {
            content {
                includeGroupByRegex("com\.android.*")
                includeGroupByRegex("com\.google.*")
                includeGroup("androidx.*")
            }
        }
        mavenCentral()
        gradlePluginPortal()
    }
}

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
    versionCatalogs {
        create("libs") {
            from(files("gradle/libs.versions.toml"))
        }
    }
}

rootProject.name = "PoPoMovies"
include(":app")

Build File

plugins {
    alias(libs.plugins.android.application)
}

android {
    namespace = "com.example.popomovies"
    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.popomovies"
        minSdk = 26
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation(libs.appcompat)
    implementation(libs.material)
    implementation(libs.activity)
    implementation(libs.constraintlayout)
    implementation(libs.glide) // not importing this
    implementation(libs.gson) // not importing this
    implementation(libs.volley) // not importing this
    testImplementation(libs.junit)
    androidTestImplementation(libs.ext.junit)
    androidTestImplementation(libs.espresso.core)
}

It also gives this error which i am not able to fix
