I am working with Android Studio, and I am trying to use google material library

I am getting the following error (Android resource linking failed):

ERROR:AAPT: C:UsersANDRESDesktopcursillo_androidTipTime2appbuildintermediatesincrementalmergeDebugResourcesmerged.dirvalues-v31values-v31.xml:3: error: resource android:color/system_neutral1_1000 not found.

Mi grade files are:

    id 'kotlin-android'
}

android {

    compileSdkVersion 30
    defaultConfig {

    }

    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0'
    implementation 'com.google.android.material:material:1.5.0-alpha05'


}

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
        jcenter()

    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.3"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.0"

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

    }
}

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


I would like to share a picture of the error with you:

  1. When your targetSdk is below 31 then the support library associated
    with material resources will be in conflict with your build configuration.

    During the build, gradle will use a task to check all support .aar libraries
    metadata, where build target compatibility is set; in the case of
    com.google.android.material:material:1.5.0-alpha05′ the target compatibility
    is set above 30 (may be 31, or even higher);
    Remedy is this:
    So go to an earlier material support library from
    here https://mvnrepository.com/artifact/com.google.android.material/material
    to use an earlier support version of the material support class;

  2. Try removing ‘implementation ‘com.google.android.material:material:1.10.0-alpha01’ in gradle(Module), works fine.
