Question

I'm seeing the following error in my Android project after updating to Gradle Build Tools 2.1.3 and Gradle 2.14.1. It happens immediately when I run the application. How do I fix this?

Answer 1

There was a bug report filed: https://code.google.com/p/android/issues/detail?id=220640

This looks to be a problem with jacoco versions. You'll need to update your jacocoversion to 0.7.6.201602180812.

To quote from the issue:

The jacoco plugin version was bumped from 0.7.4.201502262128 to 0.7.6.201602180812 between 2.1.2 to 2.1.3 which is the likely cause of this issue.

In 2.2 it is 0.7.5.201505241946.

It also looks like one possible error might be related to Google Play Services. There are temporary workarounds for the time being.

Option 1: Comment out testCoverageEnabled true.

buildTypes {
    debug {
        // testCoverageEnabled true
    }
}

Option 2: Using Instant Run also seems to solve this problem.

Answer 2

For anyone facing this error while running UI Test with jacoco code coverage using createDebugCoverageReport task

Adding this jar solved this problem
