Unable to merge dex Android Studio 3.0.1 when I run the project

Question

I have some problem with my project. In Android Studio 3.0, it works fine, but when I updated to 3.0.1, I have problem to merge dex.

I clean and rebuild project. I use multiDexEnabled true with dependency

What is wrong:

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

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

app level gradle:

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.rotaractnepalapp.rotraconversation"

Where's the `mutliDexEnabled` in your project ?. And with `multiDexEnabled` try also by using, `com.android.support:multidex:1.0.1` dependency in your project. — Aditya, Mar 02 '18 at 05:40

I'm running into the same issue. I tried enabling multidex through the instructions here, but the error persisted. I also disabled instant run, as was suggested in another post, but that made no impact. I ended up having to revert all support libraries from version 27.1.0 back to version 27.0.2. Once I did, the error was corrected with no need for any multidex configuration. There is maybe an issue with 27.1.0.

CORRECTION: I found an unused library ('android.arch.paging:runtime:1.0.0-alpha4-1') and removed it, then updated the versions back to 27.1.0 with no issue. Since your minSdkVersion is 15, be sure to follow the step 2 under the Configure your app for multidex section to ensure your application is extending the multidexapplication class.
