     You can try some of the following options:
       - changing the IDE settings.
       - changing the JAVA_HOME environment variable.
       - changing `org.gradle.java.home` in `gradle.properties`.

方案1：降级 Gradle 插件
进入 gradle-wrapper.properties 修改 Gradle 版本：

distributionBase=GRADLE_USER_HOME
distributionUrl=https://services.gradle.org/distributions/gradle-6.8.2-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

然后进入 build.gradle(Project) 修改 Android Gradle 插件版本 4.2.2：
修改为：classpath 'com.android.tools.build:gradle:4.2.2'

编译运行即可。

方案2：升级 Java 版本
