Gradle 3.0.0-beta1 build issue

Question

I just updated the gradle version to

classpath 'com.android.tools.build:gradle:3.0.0-beta1'

after updating android studio to 3.0-beta1, and my gradle-wrapper is:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip

the problem is I'm facing this weird issue when I want to Gradle-sync the project:

I've checked everything and they all look fine, can anyone help?

Answer 1

Build -> Clean project, then

Build -> Rebuild project

Answer 2

I had the same issue while trying to upgrade to 3.0.0-beta1 on Linux Mint 18.1. Nothing of the above helped: neither Clean -> Rebuild -> Sync, nor Invalidate & Restart. But Sanat's suggestion of downgrading to 2.3.3 helped

Answer 3

As per this official link this is known issue.

Known issue: 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 and sync your project: Gradle project refresh failed.

Solution: Resolve this issue by 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 menu bar.

Answer 4

I've had the same issue after the updating to beta1. Try to update your build tools to the latest version in SDK Manager -> SDK Tools. Then add the google maven to your root build.gradle like this:

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
}

This worked in my case properly

Answer 5

Try this option:

1. Leave the Gradle Sync error as is and clean the project
2. Rebuild the project
3. Now Sync the Gradle now

Note: I also did

invalidate and restart

before trying this out

It helped me, hope it helps you as well.

Answer 6

There are some known bugs in 3.0.0, This issue is one it, actually android studio is integrating Unix file system (Berkeley Fast File System) for Linux OS and it is in beta....Please downgrade your studio to 2.3.3 stable version for now.
