Answer 1

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

Answer 2

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.

Answer 3

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'
        ...

}
