解决方法：

Unity 2020.1或更高版本

这些版本是使用Gradle 5.6.4或更高版本以及Gradle插件3.6.0或更高版本构建的。无需采取任何措施。

Unity 2019.3和2019.4

注意：以下定制仅在Unity 2019.3补丁7和更高版本上受支持。

1、转到Preferences > External Tools > Android > Gradle ，然后将自定义Gradle设置为Gradle 5.6.4或更高版本。请参阅Gradle构建工具以进行下载。、

2、转到Project Settings > Player > Android tab > Publishing Settings > Build ，然后选择两者：

自定义主Gradle模板
自定义启动器Gradle模板。

3、将以下更改应用于两个生成的文件：

Assets/Plugins/Android/mainTemplate.gradle
Assets/Plugins/Android/launcherTemplate.gradle

如果存在，请在文件顶部删除以下注释：

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

在文件顶部插入以下行：

buildscript {

    repositories {

        google()

        jcenter()

    }

    dependencies {

        // Must be Android Gradle Plugin 3.6.0 or later. For a list of

        // compatible Gradle versions refer to:

        // https://developer.android.com/studio/releases/gradle-plugin

        classpath 'com.android.tools.build:gradle:3.6.0'

    }

}



allprojects {

   repositories {

      google()

      jcenter()

      flatDir {

        dirs 'libs'

      }

   }

}

2019.1和2019.2

1、转到Preferences > External Tools > Android > Gradle Installed with Unity 。清除该选项，然后指定5.6.4或更高版本的自定义版本。请参阅Gradle构建工具以进行下载。

编辑生成的文件Assets/Plugins/Android/mainTemplate.gradle ，然后根据您使用的Gradle版本将com.android.tools.build:gradle依赖项设置为3.6.0或更高版本。

buildscript {

    dependencies {

        // Must be Android Gradle Plugin 3.6.0 or later. For a list of

        // compatible Gradle versions refer to:

        // https://developer.android.com/studio/releases/gradle-plugin

        classpath 'com.android.tools.build:gradle:3.6.0'

    }

}

Unity 2018.4

注意：以下定制仅在Unity 2018.4补丁24及更高版本上受支持。

1、转到 Build Settings > Android ，然后将Build System设置为Gradle以使用自定义的Gradle版本。

2、转到Preferences > External Tools > Android > Gradle Installed with Unity 。清除该选项，然后指定5.6.4或更高版本的自定义版本。请参阅Gradle构建工具以进行下载。

3、转到 Project Settings > Player > Android tab > Publishing Settings > Build, 选择 Custom Gradle Template.

4、编辑生成的文件Assets/Plugins/Android/mainTemplate.gradle ，然后根据您使用的Gradle版本将com.android.tools.build:gradle依赖项设置为3.6.0或更高版本。

buildscript {

    dependencies {

        // Must be Android Gradle Plugin 3.6.0 or later. For a list of

        // compatible Gradle versions refer to:

        // https://developer.android.com/studio/releases/gradle-plugin

        classpath 'com.android.tools.build:gradle:3.6.0'

    }

}

按照这样配置就可以解决了，编译出错的问题。当然gradle默认的是使用google的maven地址，有时候下载编译的包会出错，可以更改自己的maven包。

buildscript {

    repositories {

        maven {

            url "https://developer.huawei.com/repo/"

        }

        google()

        jcenter()

    }

    dependencies {

        // Must be Android Gradle Plugin 3.6.0 or later. For a list of

        // compatible Gradle versions refer to:

        // https://developer.android.com/studio/releases/gradle-plugin

        classpath 'com.android.tools.build:gradle:3.6.0'

    }

}
