What went wrong:
Execution failed for task ':CoreServices:testCoverage'.
> Unable to read execution data file C:\p4\nemo\ce\sw\4.0\team\services\CoreServices\build\jacoco\testDebugUnitTest.exec
Code base:
task testCoverage(type: JacocoReport) {
reports
def mainSrc = "${project.projectDir}/src"
sourceDirectories = files([mainSrc])
def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
def debugTree = fileTree(dir: "${project.buildDir.getPath()}/intermediates/classes/debug", excludes: fileFilter)
classDirectories = files([debugTree])
// executionData = files("${project.buildDir.getPath()}/jacoco/testDebugUnitTest.exec")
executionData = fileTree(dir: project.projectDir, includes: ['**/*.exec'])
testCoverage.dependsOn('testDebugUnitTest')
}
[JENKINS-58469] Not able to generate the coverage report with jenkins jacoco plugin 1.0.19 and jacoco 0.7.4

added a comment - Depending on which version of jacoco produced the .exec file, only the matching version of the jacoco-plugin will be able to process the data.
Please at least more clearly describe which versions of jacoco and jacoco-plugin you are using here, as this is not clear from the current description.
In the long run we strongly suggest to update JaCoCo to a newer version and use the latest version of the JaCoCo-plugin, then things should work fine.
See also the note from the README/GitHub page:
Note: Version 2.0.0 and higher requires using JaCoCo 0.7.5 or newer, if your projects still use JaCoCo 0.7.4, the plugin will not display any code-coverage numbers any more! In this case please use version 1.0.19 until you can update jacoco in your codebase.

Team any suggestion on this we have to use the 1.0.19 version plugin in Jenkins and this plug in supports only jacococ version 0.7.4.
Ans using 0.7.4 we are getting the following excception.
