And in the end, the jacocoTestReport task fails as well.
The following sections of build.gradle file might be relevant:
java {
toolchain {
languageVersion = JavaLanguageVersion.of(24)
}
}
// ...
jacoco {
toolVersion = '0.8.12'
}
I originally wondered if this is a problem with Gradle, but I can also reproduce the issue by using the jacococli:
java -jar jacococli.jar instrument /build/classes/java/main/com/example/application --dest .
