在 build.gradle 中找不到参数的方法 classpath()

Question

大家好）我正在 kotlin 上制作一个关于天气的小型 Android 应用程序。我有这个问题，更改类路径不会给出任何结果。

问题

• 在 org.gradle.api.internal.artifacts.dsl.dependency 类型的对象上找不到参数 [android.arch.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha02] 的方法 classpath()。默认依赖处理程序*

构建.gradle（项目）

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"
}

Answer 1

将 buildscript 组添加到 build.gradle(Project) 文件的顶部。

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

然后将插件ID添加到build.gradle(Module)文件中的plugins组中。

id 'androidx.navigation.safeargs'

它可以帮助

Answer 2

将安全参数“类路径”更新为

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

代替

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