Android studio unable to build my app after gradle plugin updated

Question

I updated the Gradle plugin yesterday and now the android studio is not able to build my app. The app shows the following error.

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

task clean(type: Delete) {
    delete rootProject.buildDir
}

I searched this on StackOverflow and google as well. But did not find any information. Please help. I am stuck here.

I am also facing the same issue. Did you find any solution yet? — Faraz, Mar 21 '19 at 09:32

I don't have a clue why this is happening, but it is happening since yesterday, March 21 2019. I think it is a problem in the maven repository? Because the url where android studio is trying to get that library is down.

Anyway, the fix is to "manually" point AS to that missing dependency, adding this line into your build.gradle, inside dependencies{...}

implementation group: 'io.grpc', name: 'grpc-core', version: '1.16.1'

Then sync, then you can delete that line.

Well, I hope someone can explain what happened.

Adding mavenCentral() to allprojects{} section of project level build.gradle file has resolved this issue for me.

I had three build errors of the following type:

Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve io.grpc:grpc-core:[1.28.0].

As with many of these android studio related issues,

File -> Invalidate Caches / Restart...

did the trick for me.

Add mavenCentral() to your buildscripts->repositories and allprojects->repositories both places and sync the project.
