The error I get is as follows;

Exception is: org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'androidx.navigation.safeargs.kotlin'] was not found in any of the following sources:

• Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
• Plugin Repositories (plugin dependency must include a version number for this source
• Unable to load class 'com.android.build.api.extension.AndroidComponentsExtension'. This is an unexpected error. Please file a bug containing the idea.log file.

CodePudding user response：

Your project level build file is missing the allprojects -> repositories block.

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
