How to update latest gradle version of kotlin library

Question

I created a library in multiplatform in latest intellij. My intellj added the outdated gradle version settings.gradle.kts

pluginManagement {
    repositories {
        google()
        gradlePluginPortal()
        mavenCentral()
    }
    resolutionStrategy {
        eachPlugin {
            if (requested.id.namespace == "com.android") {
                useModule("com.android.tools.build:gradle:4.1.2"). // How to update to latest version and what is the use of 4.1.2?
            }
        }
    }
}
rootProject.name = "xyz"

I commented above in my code. Can someone guide how can I update my gradle version to latest and what is the use of 4.1.2 that piece of code?

I tried to remove 4.1.2 below piece of code then I am getting issue

 resolutionStrategy {
     eachPlugin {
         if (requested.id.namespace == "com.android") {
             useModule("com.android.tools.build:gradle:4.1.2")
         }
     }
 }

After @PylypDukhov suggestion, trying to update gradle 7.0.4 I am getting this weird error

error

Failed to query the value of property 'namespace'.
Package Name not found in /Users/vmodi/IdeaProjects/abc/src/androidMain/AndroidManifest.xml, and namespace not specified. Please specify a namespace for the generated R and BuildConfig classes via android.namespace in the module's build.gradle file like so:

android {
    namespace 'com.example.namespace'
}

settings.gradle.kts

pluginManagement {
    repositories {
        google()
        gradlePluginPortal()
        mavenCentral()
    }
    resolutionStrategy {

Added androidMain

Answer 1

4.1.2 is android gradle plugin version, it's not related to gradle version.

Android gradle plugin is shipped with Android Studio , if you wanna use latest version mentioned by @Egor, you have to use Android Studio .

IntelliJ IDEA supports them with a delay - the last supported version at the moment is 7.0.4 , which works fine to me, the only problem you might have with it is the lack of support for the 32 target version of Android - but it's not required to upload the app and will work fine on 32 devices, also you can build release version in AS with newest plugin, and develop in IDEA , as to me it seems more performant in KMM projects.

Answer 2

4.1.2 is the version number. To find out what the latest version is, visit Google's Maven Repository . At the time of writing, the latest stable version is 7.2.0, so simply replace "4.1.2" with "7.2.0" and rebuild the project.
