"Unable to merge dex" when using room

I'm trying to add a "room" to my project.

When I try to build a project, I get an error:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

What I have already done:

1. Clean/Rebuild project
2. I added "multiDexEnabled true" in defaultConfig{}. Then I get the error:

   Error:Execution failed for task ':app:transformClassesWithMultidexlistForDebug'. java.io.IOException: Can't write [C:\Users\user1\AndroidStudioProjects\git\mobile\app\build\intermediates\multi-dex\debug\componentClasses.jar] (Can't read [C:\Users\user1.gradle\caches\transforms-1\files-1.1\support-core-utils-26.1.0.aar\a6c34f6784b0b6bc5c2fc7a7815426da\jars\classes.jar(;;;;;;**.class)] (Duplicate zip entry [classes.jar:android/support/v4/content/PermissionChecker$PermissionResult.class]))

If I remove the "room" from my project, it is build without errors.

I'm using Android Studio 3, gradle build tools 3.0.0.

This is my build.gradle:

   dependencies {

}
