Jacoco coverage report won't reflect latest change

[jason1peng]

Describe the bug
Jacoco report was not update correctly after delete one of the tests.
Coverage report still showing object is covered.

Errors

Expected behavior
Coverage report should show object is not covered.

Reproducer
Basic project with two test file.

build.gradle.kts

plugin {
  id("org.jetbrains.kotlinx.kover") version "0.7.4"
}
...
kover {
    useJacoco("0.8.10")
}

Target class

object HelloWorld {
    fun hello() = "Hello"
    fun world() = "${hello()} World"
}

Test file 1

class HelloTest : DescribeSpec({
    describe("hello") {
        context("hello") {
            it("should return hello") {
                HelloWorld.hello() shouldBe "Hello"
            }
        }
    }
})

Test file 2

import io.kotest.core.spec.style.DescribeSpec
import io.kotest.matchers.shouldBe

class WorldTest : DescribeSpec({

    describe("world") {
        context("world") {
            it("should return hello world") {
                HelloWorld.world() shouldBe "Hello World"
            }
        }
    }

})

• trigger koverHtmlReport task, I could see HelloWorld class is covered 100%.
• delete test file 2, trigger koverHtmlReport task, HelloWorld class still covered 100%.

Thanks for the report!
The problem is not related to JaCoCo.
As workaround, you may run clean before generating the report, or use the Gradle build cache.

Thanks for the quick update. I tried these two approaches and both won't work.

1. run gradle clean before generating report.
2. use --no-build-cach

Fixed in 0.7.5
