Gradle Jacoco Plugin - Unable to load class 'org.jacoco.core.analysis.ICoverageVisitor'.

[vic zhang]

Hi all,

I try to use Jacoco plugin of Gradle 6.5 to generate code coverage report, my build.gradle looks like as:

plugins {

    id "org.sonarqube" version "3.0"
    id 'jacoco'
}

jacocoTestReport {

    reports {

        xml.enabled true

        html.enabled true

        csv.enabled false

        html.destination file("${buildDir}/jacoco")

    }

}

test.finalizedBy jacocoTestReport

But when I try to run test or jacocoTestReport task, I get following error:

Unable to load class 'org.jacoco.core.analysis.ICoverageVisitor'.

Possible causes for this unexpected error include:

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.

Stop Gradle build processes (requires restart)

Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

Does anybody know what's wrong? thanks a lot.

BR,

Vic

BTW, my Java project bases on AdoptOpenJDK 11, when I clicks on "Re-download dependencies and sync project (requires network) " link, I get below dialog which requires me to select both Android and Java JDK(otherwise, the OK button is disabled):

Hi,

neither gradle plugins not Sonarquibe are maintained by the JaCoCo project. Please see our integration matrix for pointers:

Hi Marc,

Thanks for your reply. But, Gradle donwloads Jacoco plugin which records unit tests, it seems just throw this exception at last stage(generate coverage report).

Hi,

can you show the complete stack trace?

But as said before, the Gradle project is the better place to ask.
