realmの導入をしようとするとエラーを吐く

realmの導入をしようとすると以下のようなエラーが出てしまいます。

///build.grandle(project)
buildscript {
    ext.kotlin_version = "1.4.10"
    repositories {
        google()
        jcenter()

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "io.realm:realm-grandle-plugin:10.0.0"//ここを打ち込みました

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

エラーは以下のようになりました。realmのページを参照して導入したので、手順は間違っていないと思うのですが、、、

A problem occurred configuring root project 'MyScheduler2'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not find io.realm:realm-grandle-plugin:10.0.0.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/io/realm/realm-grandle-plugin/10.0.0/realm-grandle-plugin-10.0.0.pom
       - https://jcenter.bintray.com/io/realm/realm-grandle-plugin/10.0.0/realm-grandle-plugin-10.0.0.pom
     Required by:
         project :

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