C# Unity Build错误：“；MinSDK版本1不能小于库中声明的版本15；

我尝试将我的旧Unity项目（使用Unity 2017.4）构建到Android

应用程序包中，但由于以下错误，该项目从未成功：

CommandInvokationFailure: Gradle build failed. 
C:/Program Files/AdoptOpenJDK/jdk-8.0.252.09-hotspot\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2017.4.39f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.4.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "bundleRelease"

到目前为止，我的努力是：“在Unity的插件文件夹中找到关于MinSDK的所有变量，并将其设置为15”。但是还是失败了

注意，我使用以下插件：


轻松保存3
能量棒工具包
组织核心
PlayMaker生态浏览器（自定义脚本）
多温
Dotween组织核心行动
UI分页
Doozy UI（旧版本-在资产存储中不再可用）
Ez（已弃用-在资产存储中不再可用）
TextMeshPro（旧版）

有什么想法吗？
从Unity for Android的播放器设置下拉列表中选择更高版本的API
配置“compile”已过时，并已被“implementation”和“API”取代。
@IntelliJAmiya Hi谢谢，现在它已经解决了。。。
