时隔数年回到Android项目，遭遇无法找到android-maven-gradle-plugin:2.1错误

时隔数年重新回到我的Android项目开展开发工作时，遇到了错误：Could not find com.github.dcendents:android-maven-gradle-plugin:2.1。

项目根目录build.gradle文件内容：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.6.0'
    repositories {
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        //classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath "com.github.dcendents:android-maven-gradle-plugin:2.1"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

错误输出信息：

> Could not resolve all files for configuration ':classpath'.
   > Could not find com.github.dcendents:android-maven-gradle-plugin:2.1.

• 补充仓库源：该插件不在Google仓库中，你需要在buildscript的repositories块里添加插件所在的仓库。修改后的代码如下：

buildscript {
    ext.kotlin_version = '1.6.0'
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        classpath "com.github.dcendents:android-maven-gradle-plugin:2.1"
    }
}

• 检查版本兼容性：如果补充仓库后仍报错，可尝试降级插件到1.5版本（你注释掉的那行），该版本和Gradle 4.2.1的适配性更稳定。
• 清理依赖缓存：执行命令./gradlew clean build --refresh-dependencies，清理本地Gradle缓存并重新拉取所有依赖。
