Error: Program type already present: okhttp3.Authenticator$1

在app中的build.gradle中加入如下代码，

configurations {
    all*.exclude group: 'com.google.code.gson'
    all*.exclude group: 'com.squareup.okhttp3'
    all*.exclude group: 'com.squareup.okio'
    all*.exclude group: 'com.android.support',module:'support-v13'
}

 如图
