While trying to run "gradle test jacoco" in gitbash I am getting TestExecutionException, NoClassDefFoundError, ClassNotFoundException - spring-mvc

Question

While trying to run jacoco in my gradle project, I am getting exceptions.
I have added following dependencies:
compile "org.jacoco:org.jacoco.report:0.7.8"
compile "org.jacoco:org.jacoco.core:0.7.8"
compile "org.ow2.asm:asm-all:5.1"
I also tried with different options like providedCompile, testCompile also.
I am getting this exception, while trying to run "gradle test jacoco" in gitbash.
Exceptions:
org.gralde.api.tasks: TaskExecutionException: Exception failed for
task:'practice-app:jacocoTestReport'
Caused by: java.lang.NoClassDefFoundError:
org/jacoco/report/IReportVistor
Caused by: java.lang.ClassNotFoundException:
org.jacoco.report.IReportVisitor
I also verified other checks like jacoco jars available in my local gradle repo etc.

I had also experienced the similar problem during Jacoco integration in one of our gradle project. The plugin somehow did not bring the required jars. Then, I tried to add all the dependencies manually
say :-
compile "org.jacoco:org.jacoco.report:0.7.8"
compile "org.jacoco:org.jacoco.core:0.7.8"
compile "org.ow2.asm:asm-all:0.7.8"
etc., but that trick also did not work. Still got classnotfound exception against jacoco jars. Then after a lot hit & trial, I came to know about jacocoClasspath. I did the followings:
1) First changed Jacoco version to
jacoco {
toolVersion = "0.7.8+"
}
As got some incompatibility version issue (Don't remember the exact error/exception).
2) Then, added the below code in build.gradle to ensure that required dependencies are present in the jacoco class path.
jacocoTestReport.doFirst {
configurations.testRuntime.each { jacocoClasspath += files(it); }
}
Notes:
1) doFirst will be executed before jacoco task gets executed.
2) I just added whatever present in my runtime to the jacocoClasspath. You may refine the code, to add only the required jars to the jacoco class path.
