java - Jacoco 离线检测 Gradle 脚本

Question

我尝试寻找 Jacoco 离线检测 gradle 脚本片段，但找不到。是否可以通过 gradle 脚本进行 Jacoco 离线检测？如果是的话......它的一个例子会很棒。谢谢。

Answer 1

这是使用 JaCoCo Ant Task 执行离线检测的 Gradle 脚本示例:

apply plugin: 'java'

configurations {
  jacoco
  jacocoRuntime
}

dependencies {
  jacoco group: 'org.jacoco', name: 'org.jacoco.ant', version: '0.7.9', classifier: 'nodeps'
  jacocoRuntime group: 'org.jacoco', name: 'org.jacoco.agent', version: '0.7.9', classifier: 'runtime'
  testCompile 'junit:junit:4.12'
}

repositories {
  mavenCentral()
}

task instrument(dependsOn: ['classes']) {
  ext.outputDir = buildDir.path + '/classes-instrumented'
  doLast {
    ant.taskdef(name: 'instrument',
                classname: 'org.jacoco.ant.InstrumentTask',
                classpath: configurations.jacoco.asPath)
    ant.instrument(destdir: outputDir) {
      fileset(dir: sourceSets.main.output.classesDir)
    }
  }
}

gradle.taskGraph.whenReady { graph ->
  if (graph.hasTask(instrument)) {
    tasks.withType(Test) {
      doFirst {
        systemProperty 'jacoco-agent.destfile', buildDir.path + '/jacoco/tests.exec'
        classpath = files(instrument.outputDir) + classpath + configurations.jacocoRuntime
      }
    }
  }
}

task report(dependsOn: ['instrument', 'test']) {
  doLast {
    ant.taskdef(name: 'report',
                classname: 'org.jacoco.ant.ReportTask',
                classpath: configurations.jacoco.asPath)
    ant.report() {
      executiondata {
        ant.file(file: buildDir.path + '/jacoco/tests.exec')
      }
      structure(name: 'Example') {
         classfiles {
           fileset(dir: sourceSets.main.output.classesDir)
         }
         sourcefiles {
           fileset(dir: 'src/main/java')
         }
      }
      html(destdir: buildDir.path + '/reports/jacoco')
    }
  }
}
