While trying to build an android platform in ionic after updating android studio this error started showing up.

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ’:transformClassesWithDexBuilderForDebug’. >

com.android.build.api.transform.TransformException: com.android.builder.dexing.DexArchiveBuilderException: com.android.builder.dexing.DexArchiveBuilderException:

nope, it didn’t solve my issue, but editing build.gradle file and modifying these options solved it.

compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
   }

thank you :slight_smile:
