无法从Kotlin Jacoco测试覆盖范围中排除生成的类 [英] Unable to Exclude generated classes from kotlin jacoco test coverage

问题描述

我正在尝试从jacoco覆盖率报告中排除一些生成的类. groovy可以正常工作，但是转换为Kotlin后就无法正常工作

I am trying to exclude some generated classes from jacoco coverage report. Which is working fine with groovy but after converting to Kotlin it's not working

tasks.withType<JacocoCoverageVerification> {
afterEvaluate {
     files(classDirectories.files.forEach() {
        fileTree(it).apply {
            exclude("com/generate/**")
        }
    })
}
violationRules {
    rule {
        limit {
            minimum = BigDecimal(0.30)
        }

    }

}

}

tasks.getByName("check")
.dependsOn(tasks.getByName("jacocoTestCoverageVerification"))

但是违反规则很好地工作.

But violation rule working perfectly.

推荐答案

这是kotlin上jacoco plugin的局限性.由于classDirectories不是最终的，所以我们不能采用旧的方式.我们需要使用方法classDirectories.setFrom来设置值.

It is a limitaion with jacoco plugin on kotlin. Since the classDirectories is not final, we cant go with the old way. We need to use the method classDirectories.setFrom to set the value.

tasks.withType<JacocoCoverageVerification> {
    violationRules {
        rule {
            limit {
                minimum = BigDecimal(0.62)
            }
        }
    }

    afterEvaluate {
        classDirectories.setFrom(files(classDirectories.files.map {
            fileTree(it).apply {
                exclude("com/generate/**")
            }
        }))
    }
}

tasks.withType<JacocoReport> {
    afterEvaluate {
        classDirectories.setFrom(files(classDirectories.files.map {
            fileTree(it).apply {
                exclude("com/generate/**")
            }
        }))
    }
}
