With these it helps I wrote an article a while ago about jacoco. https://github.com/uriel-frankel/android-code-coverage/ The jacoco version should change as well:
code :
apply plugin: 'jacoco'
jacoco {
   toolVersion = ''

will help you Resolved - the "includes" and "excludes" parameters of the agent refer to class names, not files.
Correct JVM agent argument for my case is:
code :
                        <!-- Doesn't work currently - waiting for JaCoCo to fix this. Moved to the Ant plugin execution. -->
                            <phase>none</phase> <!-- post-integration-test -->
                <!-- Copy JaCoCo jars to have them for the Ant plugin. -->
                        <!-- Copy the ant tasks jar. Needed for ts.jacoco.report-ant . -->
                        <execution> <id>ts.jacoco.dep.ant</id> <goals><goal>copy</goal></goals> <phase>process-test-resources</phase> <inherited>false</inherited>
                        <!-- Copy the agent jar. Needed for ${jvm.args.jacoco} to have this jar on known path.
                             If the ts.jacoco-prepare worked and really put the value into the property, this might go away. -->
                        <execution> <id>ts.jacoco.dep.agent</id> <goals><goal>unpack</goal></goals> <phase>process-test-resources</phase> <inherited>false</inherited>

                <!-- Ant plugin. -->
                        <!-- DEBUG -->

this will help I had the same problem running jacoco on an USB device. Using Genymotion solved the issue.

this one helps. I see that you already got it working, however, there's a simpler method for getting Unit Test execution data. I recently was looking into this as well, I actually made a full write up earlier today.
In my situation, I didn't want to create an additional Gradle task as I wanted the report to be generated as a part of the existing workflow. I also didn't want to explicitly add the Jacoco plugin, as Google already dups the Jacoco Ant tasks for the coverage reports for Instrumentation Tests.
code :
project.afterEvaluate {
  def append = "append=true"
  def destFile = "destfile=$buildDir/outputs/code-coverage/connected/coverage.ec"
  testDebug.jvmArgs "-javaagent:$buildDir/intermediates/jacoco/jacocoagent.jar=$append,$destFile"

  createDebugCoverageReport.dependsOn testDebug

Hope that helps Merging unit-, integration and functional tests should not be merged. They have different goals.
BUT - Cucumber tests can also be used to perform (IT) unit and/or integration testing.

I hope this helps you . This has recently improved, as Jacoco coverage verification was added to Gradle 3.4 (issue #824)!
Before Gradle 3.4, you had to resort to hand-crafted workarounds such as this one.
