Hello everyone) i am making a small android app about the weather on kotlin. And I have this problem, changing the classpath does not give anything.

Problem

• Could not find method classpath() for arguments [android.arch.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha02] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler*

build.gradle(project)

plugins {
    id 'com.android.application' version '7.2.0' apply false
    id 'com.android.library' version '7.2.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
}

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

dependencies {
    classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha02"
}

update the Safe args "classpath" to

 val nav_version = "2.4.2"
    classpath("androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version")

instead of

    classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha02"

CodePudding user response：

Add a buildscript group to the top of the build.gradle(Project) file.

buildscript {
dependencies {
    classpath("androidx.navigation.safeargs:androidx.navigation.safeargs.gradle.plugin:2.4.1")
   }
}

Then add the plugin ID to the plugins group in the build.gradle(Module) file.

id 'androidx.navigation.safeargs'

It can help to
