错误：

错误：未找到Gradle DSL方法：“ implementation（）” 可能的原因：项目``Exceltest''可能正在使用不包含该方法的Android Gradle插件版本（例如，在1.1.0中添加了``testCompile''）。将插件升级到3.5.2版并同步项目

项目“ Exceltest”可能正在使用不包含该方法的Gradle版本。打开Gradle包装器文件

构建文件可能缺少Gradle插件。应用Gradle插件

事件日志： 18:27 Gradle同步失败：在类型org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler的对象上找不到参数[androidx.appcompat：appcompat：1.1.0]的方法Implementation（）。（950毫秒）

18:27 NDK分辨率结果：项目设置：Gradle模型版本= 5.4.1，NDK版本为UNKNOWN

18:28运行“ Exceltest”时出错：Gradle项目同步失败。请修复您的项目，然后重试。

在升级到Android Studio v3.5.2之前，一切正常，尝试了AS提供的所有建议，但是我在尝试手动更新（gradle升级和工具升级）方面遇到了困难。我是AS的新手，我看过以前的答案，但它们与许多旧版本有关，或者我的版本中不存在文件系统。请有人帮忙吗？

Answer 2

项目的build.gradle文件中有错误。看起来应该像这样

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

一切似乎都很好，但是， 1 。您迁移到Androidx的某些库，有些没有迁移，所以我要求您将项目的所有库迁移到androidx。 2 。从您的项目级别gradle文件中删除实施行，或将其移至App级别gradle文件。
