app:transformClassesWithDexBuilderForDebug

Olá, pessoal.

Meu app não está rodando. Aparece a mensagem

app:transformClassesWithDexBuilderForDebug
> com.android.build.api.transform.TransformException: com.android.builder.dexing.DexArchiveBuilderException: com.android.builder.dexing.DexArchiveBuilderException: Failed to process C:\Users\Thiago\.gradle\caches\modules-2\files-2.1\com.squareup.okhttp3\okhttp\3.14.9\3e6d101343c7ea687cd593e4990f73b25c878383\okhttp-3.14.9.jar

Invoke-customs are only supported starting with Android O (--min-api 26)

Incluí a dependência compile 'com.android.support:multidex:1.0.0', coloquei multiDexEnabled true e também

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8

    }

mas mesmo assim está dando o erro:

Execution failed for task ':app:transformClassesWithDexBuilderForDebug'.
> com.android.build.api.transform.TransformException: java.lang.RuntimeException: java.lang.RuntimeException

O que faço? O.O
