JaCoCo XML 报告未生成代码覆盖率

Question

我目前有一个 gradle 用于 KMM 多平台库的构建脚本，如下所示。我正在尝试使用 JaCoCo 来报告测试结果和代码覆盖率。我可以在 HTML 中的某个地方看到测试结果，但我看不到任何地方生成的测试结果和代码覆盖率的 XML 报告。我如何更改此 gradle 文件以便生成 XML 报告？
我正在使用 ./gradlew testCoverage

PS.: 我故意在代码中屏蔽了一些敏感的字符串。

我有一个类似的问题并通过指定源目录和执行数据解决了它。您可能需要根据您的项目更改这些值。

    sourceDirectories.setFrom(files(project.projectDir))
    executionData.setFrom(
            fileTree(project.projectDir) {
                setIncludes(setOf("**/**/*.exec", "**/**/*.ec"))
            }
    )
