JaCoCo evaluation report is failed during measuring coverage in run_with_coverage.sh script

[amandelpie]

Description

The section of the documentation https://github.com/UnitTestBot/UTBotJava/blob/main/docs/jlearch/setup.md#continue-setup
could not be reproduced correctly

The JaCoCo report is not generated.

To Reproduce

1. Train the minimal model according provided instruction
2. Run the last step to measure the quality of the model
3. Obtain a few errors: a few failed tests due to the row ./gradlew :utbot-junit-contest:test :utbot-junit-contest:jacocoTestReport
4. If comment first part with running tests, you will obtain the failing of report generation
5. If run the :utbot-junit-contest:jacocoTestReport with flags --stacktrace you could find the real reason

Expected behavior

Report should be generated

Actual behavior

Got the following stacktrace

Additional context

The following solution solves the problem:

1. Change gradle script in the

jacocoTestReport {
    doFirst {
        delete fileTree (dir: "${buildDir}/resources/main/lib")
    }
    reports {
        html.enabled = true
    }
}

It removes the utbot-instrumentation.jar from the analyzing path
2. Run ./gradlew :utbot-junit-contest:assemble
3. Re-run the run_with_coverage.sh script like the following command ./scripts/run_with_coverage.sh antlr 10 "NN_REWARD_GUIDED_SELECTOR models/linear/0" linear0 true
4. The report is found under eval/jacoco
