Gradle同步失败：无法找到com.amitshekhar.android:debug-db:1.0.6依赖

问题根源分析 #

1. buildscript块配置位置错误：你将buildscript块嵌套在android块内部，这违反了Gradle配置规范，会导致构建脚本依赖的仓库配置无法正常生效。
2. 模块级依赖仓库缺失：应用依赖（如debug-db）需要的仓库未在模块层级配置——buildscript中的仓库仅作用于构建脚本的classpath依赖，不覆盖应用级依赖的查找范围。
3. 未定义变量：testImplementation "org.mockito.kotlin:mockito-kotlin:$mockitoKotlinVersion"中的mockitoKotlinVersion未声明，会引发额外同步错误。

修复步骤 #

1. 调整buildscript块位置 #

将buildscript块移到模块级build.gradle最外层，与plugins、android块同级，并补充未定义的变量：

buildscript {
    ext {
        agp_version = '8.1.1'
        mockitoKotlinVersion = "4.1.0" // 补充未定义的Mockito Kotlin版本变量
    }
    repositories {
        maven { url 'https://jitpack.io' }
        google()
        mavenCentral()
    }
    dependencies {
        def nav_version = "2.7.1"

        classpath("androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version")
        classpath "com.android.tools.build:gradle:$agp_version"
        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.10'
    }
}

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'org.jetbrains.kotlin.plugin.parcelize'
    id 'com.google.devtools.ksp'
    id 'org.jetbrains.kotlin.kapt'
    id 'androidx.navigation.safeargs.kotlin'
}

2. 添加模块级依赖仓库 #

在plugins块之后、android块之前添加repositories块，配置应用依赖所需的仓库：

repositories {
    google()
    mavenCentral()
    maven { url 'https://jitpack.io' }
}

3. 清理重复依赖（可选） #

移除dependencies块中的重复依赖，避免冗余：

• 重复的implementation 'com.google.android.material:material:1.9.0'
• 重复的androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
