Can someone help me?

Answer 1

Your project :app is missing a butter knife reference. From the documentation this is what you are missing:

repositories {
    mavenCentral()
}

Also, the version you are using 5.1.2 does not exists:

{ "errors" : [ { "status" : 404, "message" : "Could not find resource" } ] }

Try the following file:

apply plugin: 'com.android.application'

buildscript {
    repositories {
        google()
        mavenCentral()
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

android {
    compileSdkVersion 26
    buildToolsVersion '28.0.3'

    defaultConfig {
        applicationId "com.wakeup.xxx"
        minSdkVersion 18
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

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

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    implementation 'com.android.support:appcompat-v7:25.1.1'
    testImplementation 'junit:junit:4.12'
