Gradle sync failed after upgrade to Android Studio 3.0 Beta 1

Question

A project syncing and building OK when on Android Studio 3.0 Canary 9. Just started failing the Gradle sync immediately after the upgrade to Android Studio 3.0 Beta 1!

Using the Android Studio bundled Java 8 without hacks on a Debian GNU/Linux 9 (Stretch, stable, up-to-date).

UPDATE: Solved with Beta 2

https://androidstudio.googleblog.com/2017/08/android-studio-30-beta-2.html

Note: additional effort needed on rewriting code to avoid problematic Java libs for Android.

UPDATE: First try from Google

https://androidstudio.googleblog.com/2017/08/android-studio-30-beta-1.html

Several issues arise (e.g., errors about signature-polymorphic method without --min-sdk-version >= 26)

These issues were not present on Canary 9!

    Error:Execution failed for task ':app:transformClassesWithDexBuilderForDebug'. > com.android.build.api.transform.TransformException: org.gradle.tooling.BuildException: com.android.dx.cf.code.SimException: signature-polymorphic method called without --min-sdk-version >= 26 

(Google's nonsolution)

Answer 1

UPDATE: Android Studio 3.0 Beta 3

With the following list of bug fixes:

Seems like this issue is already gone. After Updating from 3.0 Beta 2 to 3.0 Beta 3, I don't have to manually clean the project.

UPDATE: Android Studio 3.0 Beta 2

From the official Android Studio 3.0 Beta 2 known issues:

If you have an existing Android Studio project that's using an alpha version of Android plugin 3.0.0 (such as 3.0.0-alpha9), you may get the following error when you migrate to Android plugin 3.0.0-beta1 (or higher) and sync your project: Gradle project refresh failed.

Resolve this issue by selecting Build > Clean Project from the menu bar.

Answer 2

You can fix this issue by doing this:
