I have a problem when using Android Studio 3. when using variant debug run well. Anyone can help?

classpath 'com.google.gms:google-services:3.1.0'


distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip

Caused by: groovy.lang.MissingMethodException: No signature of method: com.android.build.gradle.internal.core.GradleVariantConfiguration.getFlatPackageAndroidLibraries() is applicable for argument types: () values: [] at com.guardsquare.dexguard.cU.getProguardFiles(DexGuard7.3.11:1337) at com.guardsquare.dexguard.dl.doCall(DexGuard7.3.11:262) at org.gradle.api.internal.AbstractTask$ClosureTaskAction.execute(AbstractTask.java:722) at org.gradle.api.internal.AbstractTask$ClosureTaskAction.execute(AbstractTask.java:695) at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter$1.run(ExecuteActionsTaskExecuter.java:121) at org.gradle.internal.progress.DefaultBuildOperationExecutor$RunnableBuildOperationWorker.execute(DefaultBuildOperationExecutor.java:336)

I think this problem because gradle cannot access dexguard file. So, we wait for dexguard fixed it.

gradle android

Once I upgraded Android Studio 3.1, I had the same issue. I download the latest Dexguard 8.2.05 and it solved this problem.

I think that if you are running Android Studio 3 and you should upgrade Dexguard to 8.2. This combination solved my issue.
