引入百度的sdk,报这个错该怎么解决?半天没找到原因

1.开源库地址: https://github.com/PaddlePaddle/LiteKit

2.gradle:

    minSdkVersion 15
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

    }
}

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

它这不是有文档吗？没有上传到maven仓库，需要你克隆下来本地引入。我就搞不懂，文档摆在那里，你不好好看文档，有啥好问的

build.gradle(project)需要配置一下maven
