Compilation failed to complete:Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

Question

I don't understand why the compilation failed to complete:

compilation failed to complete:Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

This is what I have:

apply plugin: 'com.android.application'
apply plugin: 'realm-android'


android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "ge.redefine.eomer9"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 5
        versionName "1.2.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    useLibrary 'org.apache.http.legacy'
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    testImplementation 'junit:junit:4.12'
    implementation('com.github.afollestad.material-dialogs:core:0.8.5.8@aar') {
        transitive = true

    }
    implementation 'com.android.volley:volley:1.1.0'
    implementation 'com.android.support:appcompat-v7:27.1.1'

    annotationProcessor 'org.parceler:parceler:1.1.9'
    implementation ('com.weiwangcn.betterspinner:library-material:1.1.0') {
        exclude group: 'com.android.support', module: 'appcompat-v7'
    }
}

I had the same problem with aar. Try compileOnly instead of for implementation

compileOnly "com.github.silvestrpredko:dot-progress-bar:0.1.4@aar"
