How to downgrade android support library

问题

I updated sdk to 27.1.0 but now i want to downgrade to 27.0.2 My build.gradle contains these lines:

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'
apply plugin: 'project-report'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'
    defaultConfig {
        applicationId "cz.my.package"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 73
        versionName "1.1.5"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

greendao {
    schemaVersion 6
}

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-v7:27.0.2'
    implementation 'com.android.support:support-v4:27.0.2'
    implementation 'com.android.support:design:27.0.2'
    implementation 'com.android.support:recyclerview-v7:27.0.2'
    implementation 'com.google.android.gms:play-services-maps:11.8.0'
    implementation 'com.google.firebase:firebase-messaging:11.8.0'
    implementation 'com.github.bumptech.glide:glide:4.0.0'
    implementation 'com.jakewharton:butterknife:8.8.1'
    implementation 'de.hdodenhof:circleimageview:2.1.0'
    implementation 'org.apmem.tools:layouts:1.10@aar'
    implementation 'com.davemorrissey.labs:subsampling-scale-image-view:3.6.0'
    implementation 'com.thoughtbot:expandablerecyclerview:1.3'
    implementation 'in.championswimmer:SimpleFingerGestures_Android_Library:1.2'
    implementation 'org.greenrobot:greendao:3.2.2'
    implementation 'com.kyleduo.switchbutton:library:2.0.0'
    implementation 'com.theartofdev.edmodo:android-image-cropper:2.6.0'
    implementation 'cz.martinforejt:swipetohidelayout:1.0.4'
    implementation 'org.apache.commons:commons-lang3:3.4'
    testImplementation 'junit:junit:4.12'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
    implementation files('libs/YouTubeAndroidPlayerApi.jar')
    implementation 'org.jetbrains:annotations-java5:15.0'
}

apply plugin: 'com.google.gms.google-services'

But android studio says, that it founds some lib with version 27.1.0 and all must have same version. Another problem is that i cant find 27 folder inside sdk/extras/android/m2repository/com/android/support/

How can i downgrade support libraries?
