编译成jar方法：
https://blog.csdn.net/yaojie5519/article/details/89968658

task makeJar(type: Copy){
    
    
    delete 'build/libs/sdk.jar'
    from('build/intermediates/packaged-classes/release/')
    into('libs/')
    include('classes.jar')
    rename('classes.jar', 'sdk.jar')
}

如果我们将：C:\Program Files\Unity Hub\Unity\Editor\Data\PlaybackEngines\AndroidPlayer
下的source文件夹删除掉，打包之后会崩溃。报：

java.lang.ClassNotFoundException: Didn't find class "com.unity3d.player.UnityPlayerActivity" on path: DexPathList[[zip file "/data/app/com.DefaultCompany.op_xlua-1/base.apk"]
