Unable to Merge Dex Android Studio 3.0 after update

Question

updated my project to gradle 3 and generated this error

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

in another questions says "libraries having transitive dependency " but i don't find the library with this transitive dependency

build.gradle app apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'
    compileOptions.encoding = 'UTF-8'
    useLibrary 'org.apache.http.legacy'
