Problems with using open source(cannot resolve com~~)

Question

masters. I've just started developing an Android(kotlin). I tried to use open source for my project, but there is an error. What am I supposed to do here? (I referred to "https://androidexample365.com/customizable-timetableview-for-android/")

my project's gradle(module)-----------------------------------------------------------------------

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-android-extensions'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.akj.callback"
        minSdkVersion 23
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}
dependencies {
    implementation 'com.github.islandparadise14:Mintable:x.y.z'
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.6.0'
    implementation 'androidx.appcompat:appcompat:1.3.0'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    implementation "com.airbnb.android:lottie-compose:1.0.0-rc02-1"
}

my project's gradle(Project)----------------------------------------------------------------------

buildscript {
    ext.kotlin_version = "1.5.21"
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // 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
        maven { url uri("https://jitpack.io") }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

my project's xml----------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".test_timetable">

    <com.islandparadise14.mintable.MinTimeTableView
        android:id="@+id/table"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
    
</androidx.constraintlayout.widget.ConstraintLayout>

error message-------------------------------------------------------------------------------------

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Could not find com.github.islandparadise14:Mintable:x.y.z.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/com/github/islandparadise14/Mintable/x.y.z/Mintable-x.y.z.pom
       - https://repo.maven.apache.org/maven2/com/github/islandparadise14/Mintable/x.y.z/Mintable-x.y.z.pom
       - https://jcenter.bintray.com/com/github/islandparadise14/Mintable/x.y.z/Mintable-x.y.z.pom

     Required by:
         project :app

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html`enter code here`

I did not touch any of the above settings. I just want to use this off-source for my project. I'd like to solve this problem.

See the reference on jitpack's page. Use the latest version, or any other version that is fit for your purpose.

When you declare a remote dependency in your module-level Gradle file (written in Groovy or Kotlin), the format is generally like this:

implementation '{package/group}:{module/project}:{versionNumber}'

// Example: 'com.example.android:app-magic:12.3'
// which is shorthand for:

implementation group: 'com.example.android', name: 'app-magic', version: '12.3'

See the Android docs for more info.

Here, the module/project name may or may not be present, as it is typically optional for the creator of the library/module to generate or use. Thus, in the case of the Mintable project, to use the newest version, you would use:

implementation 'com.github.islandparadise14:Mintable:1.5.1'  //in place of x.y.z

Hope this information is also helpful in the future. All the best!
