title: Gradle DSL method not found : 'multiDexEnabled()'
body: <p>I followed the multidex guide at <a href="https://developer.android.com/tools/building/multidex.html" rel="noreferrer">https://developer.android.com/tools/building/multidex.html</a></p>
  
  <p>But I get this error <strong>Gradle DSL method not found : 'multiDexEnabled()'</strong> . I have updated Android Built Tools , Android Support Repository and Library. Here is my gradle.build file. Am I doing something wrong here?</p>
  
  <pre><code>Could not find method multiDexEnabled() for arguments [true] on ProductFlavorDsl_Decorated{name=main, minSdkVersion=ApiVersionImpl{mApiLevel=10, mCodename='null'}, targetSdkVersion=ApiVersionImpl{mApiLevel=17, mCodename='null'}, renderscriptTargetApi=-1, renderscriptSupportMode=null, renderscriptNdkMode=null, versionCode=-1, versionName=null, applicationId=test.com.app, testApplicationId=null, testInstrumentationRunner=null, testHandleProfiling=null, testFunctionalTest=null, signingConfig=null, resConfig=null}.
