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

recquired online for until fix the error (fixing the gradle error.after successfully fixed the errror.you can work in offline.)
1.download latest gradle from ->https://gradle.org/releases
2.after downloading the zip files,it extract all the files into a folder (for good work:-name the folder 'gradle4',place the samelocal disc where your android studio installed eg-you installed android studio in local disc :c if place the 'gradle4' in local disc c)
3.android studio->file menu->settings->build,Excecution,Deployment->Gradle
4.check-use local gradle distribution
5.give gradle folder path into the gradle home optionScreen shot of gradle setting step 5

6.Enable embedded Maven Repository Screen shot of Enable Maven Repository

click ->apply
Build menu->clean project
-problem solved-

Answer 2

Following solutions didn't work for me :

1. Pressing that try again button again and again
2. Using offline and online gradle changes
3. Cleaning, syncing or rebuilding.

Solution:

After all these I just visited ~/.gradle folder, it contains a single folder named wrapper, just rename it to anything else i.e. wrapper123. That's it problem solved !!!! Press build and it will start syncing and building the project

Answer 3

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 4

I'm on Android Studio 3.0 Beta 2, and I found that on top of the clean and sync proposed here, for my project which was Java-Kotlin-mixed code base, I had to drop my Kotlin version to 1.1.3-2, which is the IDE bundled version, clean & sync then works, and then I can bring the Kotlin version back to 1.1.4 which is latest at the time of writing.

Answer 5

There is a solution offered by Google:

Resolve this issue selecting Build > Clean Project from the menu bar. You need to perform this action only once for each project. You can then sync your project files with Gradle by clicking Sync Project from the toolbar.

Answer 6

You can fix this issue by doing this:

Build > Clean Project

Answer 7

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

1. Open the Terminal window by selecting View > Tool Windows > Terminal from the menu bar.
2. Delete all intermediate and cached build files with the following command: gradlew clean.
3. Build your project with the following command: gradlew assemble.
4. Sync your project files with Gradle by clicking Sync Project from the toolbar.

Or as I did, open the tab "Gradle" and run "clean" and then "assemble" like this:

Go to your right at Android Studio, open the tab "gradle", then in ":app"/"Tasks"/"build" you will see "clean", "assemble" and other tasks.

Run first clean and then assemble, you may get an error but it still works and finally rebuild your project.
