Android: невозможно синхронизировать c старый проект, невозможно разрешить зависимость для ':app@debug/compileClasspath': не удалось устранить ошибку

Question

Я попытался открыть старый проект, который мне не принадлежит, но он не может синхронизировать c и правильно построить с ошибками Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve de.keyboardsurfer.android.widget:crouton:1.8.5. Show Details Affected Modules: app ошибка отображается почти для каждой зависимости, i tried invalidating caches and restarting, cleaning the project and adding google to reporsitories.

here is my project gradle file:

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

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }

    }
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'

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

allprojects {
    repositories {
        jcenter{ url "http://jcenter.bintray.com/" }
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

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

here is the app module gradle file:

Я должен упомянуть, что это новая работа, и этот проект был сделан старым разработчиком 4 года go, и мне нужно изменить некоторые вещи внутри приложения (изменение listViews с помощью recyclerViews например).
