如何修复 gradle 中无法在 Android Studio 中构建应用程序的错误？

Question

An error occurs during build:

Gradle sync failed: Could not get unknown property 'build' for root project 'Svetofor' of type org.gradle.api.Project.

Code where the error occurs build.gradle (Svetofor):

build.gradle(Project: AndroidStudioProjects)
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'
buildscript {
    repositories {
        google()
        mavenCentral()

    }




// Top-level build file where you can add configuration options common to all sub-projects/modules.


    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.properties:

# Enables namespacing of each library's R class so that its R class includes only the
