There seems to be a problem with the version "1.28.0" of "io.fabric.tools:gradle".

I corresponded as follows

classpath 'io.fabric.tools:gradle:1.+'

Change to the following code

classpath 'io.fabric.tools:gradle:1.27.1'

I hope the fabric team will respond

Its problem with fabric tools that added in build.gradle app level

To solve this issue

go to build.gradle app level and find the below code

change this

 dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }

to this

dependencies {
    classpath 'io.fabric.tools:gradle:1.27.1'
}

try with other versions like 1.28 if above version not working. avoid using + in version codes and also that stops the auto update.

In my case, the Gradle Build Task was failing with the latest version(1.28.0) of Fabric Gradle Plugin. Downgrading to version 1.27.1 resolved this issue. There has been a Fabric Gradle Plugin release recently on 15th March 2019.

For users facing this issue and have added the Fabric Gradle Plugin as

dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
        ...

}

need to replace with

dependencies {
        classpath 'io.fabric.tools:gradle:1.27.1'
        ...

}
