Andoid Studio 3.4
app / build.gradle：
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 18
targetSdkVersion 28
versionCode 427
versionName "2.1.427"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
implementation 'com.crashlytics.sdk.android:crashlytics:2.9.7'
implementation 'com.google.android.gms:play-services-gcm:16.0.0'
implementation 'com.google.code.gson:gson:2.8.2'
implementation 'com.j256.ormlite:ormlite-android:5.1'
implementation 'commons-codec:commons-codec:1.11'

implementation 'org.apache.httpcomponents:httpclient:4.5.8'
implementation "org.androidannotations:androidannotations-api:$AAVersion"
implementation "org.androidannotations:ormlite-api:$AAVersion"
但是在这一行中我得到了错误：
implementation 'org.apache.httpcomponents:httpclient:4.5.8'
httpclient defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. more...
