【问题描述】：

我已经使用 Flutter 在 VS Code 上创建了一个应用程序，并且在我开始准备构建应用程序之前没有遇到任何问题。我开始将包名称从“com.example.careona19”更改为“com.covid19rsa.app”，但随后开始出现此错误：

```Launching lib\main.dart on VOG L09 in debug mode...

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\pkirby\development\careona19\android\app\build.gradle' line: 24

* What went wrong:
A problem occurred evaluating project ':app'.
> Plugin with id 'com.covid19rsa.app' not found.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Android 级 build.gradle：

```buildscript 
    ext.kotlin_version = '1.3.50'
    repositories 
        google()
        jcenter()
    

    dependencies 
        classpath 'com.android.tools.build:gradle:3.6.1'
        //classpath 'com.android.tools.build:gradle:3.5.0' - original

rootProject.buildDir = '../build'
subprojects 
    project.buildDir = "$rootProject.buildDir/$project.name"

subprojects 
    project.evaluationDependsOn(':app')


task clean(type: Delete) 
    delete rootProject.buildDir

```

应用级 build.gradle：

```def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) 
    localPropertiesFile.withReader('UTF-8')  reader ->
        localProperties.load(reader)
    


def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) 
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")


def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) 
    flutterVersionCode = '1'


def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) 
    flutterVersionName = '1.0'


apply plugin: 'com.covid19rsa.app'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
//apply plugin: 'com.google.gms.google-services'

def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) 
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

```

我一直在尝试所有我能找到的解决方案，但似乎没有任何效果。我有什么明显的遗漏吗？

【问题讨论】：

在应用级gradle中，使用apply plugin: 'com.covid19rsa.app'而不是apply plugin: 'com.android.application'

@MidhunMP - 更新后，我仍然收到错误：* 出了什么问题：。 > 无法应用插件 [id 'com.android.internal.version-check'] > 支持的最低 Gradle 版本为 5.6.4。当前版本是 5.6.2。如果使用 gradle 包装器，请尝试将 C:\Users\pkirby\development\careona19\android\gradle\wrapper\gradle-wrapper.properties 中的 distributionUrl 编辑为 gradle-5.6.4-all.zip

尝试更新你的 gradle 版本

@MidhunMP - 现在完美运行......谢天谢地，我快要流泪了。请在答案部分添加您的答案，以便我将其标记为正确答案。谢谢！

不客气。快乐编码！！！

【参考方案1】：

这一行的问题：

apply plugin: 'com.covid19rsa.app'

你必须使用：

apply plugin: 'com.android.application'
