InvalidPluginRequestException Gradle AndroidStudio

问：

我在 2 个月后导入了现有的 android 项目，当它开始同步 gradle 时，它给出了一些奇怪的错误，因为早些时候该项目运行正常。 错误是Caused by: org.gradle.plugin.management.internal.InvalidPluginRequestException: Plugin 'com.android.application' is already on the script classpath.

下面是我的 gradle 文件：build.gradle （：app）

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'

我试图为此找到解决方案，但没有找到可以解决此问题的正确解决方案，任何人都可以帮助我解决这个问题和这个新的 gradle 插件调用。

Android版本 ： Android Studio Arctic Fox |2020.3.1 补丁 3， Gradle 版本：4.1， Android gradle 插件版本：3.0.1
