Run a gradle command to run a test. Make sure that gradle wrapper downloads Gradle 4.10 version.

FATAL ERROR in native method: processing of -javaagent failed

Expected output: What specifically did you expect to happen?

The tests should be running.

Alternatives: What else have you tried, actual/expected?

Tried changing the JaCoCo version to be 0.8.1 and also tried to have no tool version in the apply plugin section of the build.gradle.

This time the exception was a little different. Posting those stack traces. Instead of java/util/UUID, we are seeing Class java/lang/UnknownError

Found the following when searching for a solution:

Fixed this error changing Java SDK in my project from 14 to 11 and my tests started working fine. Solution: IntellijIDEA: File > Project Structure > Project Tab > SDK adopt-opendjdk-11 (in my case for Ubuntu). Hope that helps anyone out there. https://stackoverflow.com/questions/59945979/java-lang-nosuchfieldexception-erreor-from-jacoco/64230649#64230649

I notice that the 0.8.0 release of jacoco may have fixed some aspects of the issue and that the most recent release is 0.8.6

After we've confirmed that upgrading to Gradle 6.7 didn't introduce any regressions, should we experiment with the 0.8.6 or 0.8.5 jacoco plugin including adding:

• the plugin in the parent build.gradle and
• the report generation in marklogic-client-api-functionaltests/build.gradle

The usage may have changed in Gradle 6.7 and the jacoco 0.8.6 plugin. If so, the following command would report the deprecations in our usage:

./gradlew help --warning-mode all

For convenience, capturing the link for the jacoco plugin documentation:

https://docs.gradle.org/current/userguide/jacoco_plugin.html

jacoco is no longer part of the project, removing
