我如何验证一些排除类和jacoco插件的最小覆盖率？

Question

我需要检查新jacoco任务的最小覆盖范围

Jacocotestcoverageverization

gradle版本3.4.1和jacoco插件>=0.6.3提供了此任务

我可以运行另一个任务，生成带有分支覆盖率的html报告，但现在我想使用这个数字来使构建失败。

buildscript {
    ext {
        ....
    }
    repositories {
        mavenCentral()
        maven {
            ....
        }
    }
    dependencies {
        .....
    }
}


apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'jacoco'

jar {
    baseName = "coverage-test"
}


dependencies {
    // my dependencies
}


eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
    }
}

wrapper {
    gradleVersion = '3.4.1'
}

jacoco {
    toolVersion = '0.7.9'
}

jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
    }    
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)

    afterEvaluate {
        classDirectories = files(classDirectories.files.collect {
            fileTree(
                dir: it,
                excludes: 
                [
                        'com/jacoco/dto/**',
                        'com/jacoco/configs/**', 
                        //and others
                ])
        })
    }
}

jacocoTestCoverageVerification {

    //I tried this and it didn't work

  //   classDirectories = files(classDirectories.files.collect {
  //   fileTree(
  //    dir: it,
        // excludes: 
        // [
        //      'com/jacoco/dto/**',
        //      'com/jacoco/configs/**', 
        //      //and others
        // ])
  //   })

    violationRules {
        rule {
            //Also tried this and it didn't work

           // excludes = ['com/jacoco/dto/**', ...]

            limit {
                counter = 'BRANCH'
                minimum = 0.8
            }
        }
    }
}
check.dependsOn jacocoTestCoverageVerification

在我的例子中，我确实希望使用BUNDLE作用域为整体设置阈值，同时排除某些包和文件。

对我来说，最后起作用的是添加classdirectoriesexclude，就像最初的问题中建议的那样，但是在afterevalue中，如下所示：

afterEvaluate {
        classDirectories = files(classDirectories.files.collect {
            fileTree(dir: it, exclude:  [
                    'com/example/my/package/*',
                    'com/example/service/MyApplication.class',
                    'com/google/protobuf/*'
            ])
        })
    }

作为参考，完整的build.gradle如下所示：

apply plugin: "jacoco”

jacocoTestCoverageVerification {
    afterEvaluate {
        getClassDirectories().setFrom(classDirectories.files.collect {
            fileTree(dir: it, exclude:  [
                    'com/example/my/package/*',
                    'com/example/service/MyApplication.class',
                    'com/google/protobuf/*'
            ])
        })
    }

    violationRules {
        rule {
            limit {
                minimum = 0.79
            }
        }
    }
}


// to run coverage verification during the build (and fail when appropriate)
check.dependsOn jacocoTestCoverageVerification
