使用jacocoTestCoverageVerification的安卓检查代码覆盖率阈值
我想要的：
我想在Android gradle中匹配代码覆盖率阈值到最小值，比如60%等。
我尝试过的东西
stack overflow question i have looked into
我正面临的问题
我的Gradle文件是这样写的：
apply plugin: 'com.android.application'
apply plugin: 'jacoco'
jacoco {
toolVersion = "0.7.6.201602180812"
reportsDir = file("$buildDir/customJacocoReportDir")
}
def coverageSourceDirs = [
'src/main/java',
]
jacocoTestReport {
reports {
xml.enabled false
csv.enabled false
html.destination "${buildDir}/jacocoHtml"
}
}
jacocoTestCoverageVerification {
violationRules {
rule {
limit {
minimum = 0.5
}
}
rule {
enabled = false
element = 'CLASS'
includes = ['org.gradle.*']
limit {
counter = 'LINE'
value = 'TOTALCOUNT'
maximum = 0.3
}
}
}
}现在，当我同步我的gradle文件时，我遇到了以下错误
在类型为org.gradle.api.Project的项目':app‘上找不到参数build_5t0t9b9hth6zfihsyl5q2obv8$_run_closure2@41a69b20的方法jacocoTestReport()。
如果我注释jacocoTestReport任务，那么
在类型为org.gradle.api.Project的项目':app‘上找不到参数build_5t0t9b9hth6zfihsyl5q2obv8$_run_closure2@3da790a8的方法jacocoTestCoverageVerification()。
我不能理解这里到底发生了什么。为什么jacocoTestCoverageVerification方法不在插件中。我做错了什么。
是不是gradle从android插件中选择了jacoco插件？
我已经尝试过提到jacocoTestCoverageVerification版本到0.6.3，正如文档中提到的那样，have方法是在这个版本之上编写的。
如果有人能解决这个问题，那将是非常有帮助的。
如果需要任何其他信息，请让我知道。
谢谢

这个问题一直困扰着我好几次，每次关键字android jacocoTestCoverageVerification将我带到这个页面，但没有得到任何答案。最后，我成功地让jacoco工作了，我想在这里分享我的解决方案。
gradle找不到jacocoTestCoverageVerification和jacocoTestReport的原因是For projects that also apply the Java Plugin, the JaCoCo plugin automatically adds the following tasks jacocoTestReport and jacocoTestCoverageVerification。这意味着对于没有应用java插件的项目，它不会添加 jacocoTestReport和jacocoTestCoverageVerification。
所以我们必须自己添加它们。
点击链接：Code Coverage for Android Testing，我们可以添加任务jacocoTestReport。
用和一样的方式，我们也可以添加任务jacocoTestCoverageVerification。
完整函数如下所示
// https://engineering.rallyhealth.com/android/code-coverage/testing/2018/06/04/android-code-coverage.html
ext.enableJacoco = { Project project, String variant ->
project.plugins.apply('jacoco')
final capVariant = variant.capitalize()
StringBuilder folderSb = new StringBuilder(variant.length() + 1)
for (int i = 0; i < variant.length(); i++) {
char c = variant.charAt(i)
if (Character.isUpperCase(c)) {
folderSb.append('/')
folderSb.append(Character.toLowerCase(c))
} else {
folderSb.append(c)
}
}
final folder = folderSb.toString()
project.android {
buildTypes {
debug {
testCoverageEnabled true
}
}
testOptions {
unitTests.all {
jacoco {
//You may encounter an issue while getting test coverage for Robolectric tests.
//To include Robolectric tests in the Jacoco report, one will need to set the includeNolocationClasses flag to true.
// This can no longer be configured using the android DSL block, thus we search all tasks of Test type and enable it
includeNoLocationClasses = true
}
}
}
jacoco {
version = '0.8.1'
}
}

toolVersion = '0.8.1'

首先检查你的gradle verison:对于也应用了Java插件的项目，JaCoCo插件会自动添加以下任务：
Gradle3.3 (jacocoTestReport任务) https://docs.gradle.org/3.3/userguide/jacoco_plugin.html#sec:jacoco_tasks
Gradle3.5 (jacocoTestReport，jacocoTestCoverageVerification任务) https://docs.gradle.org/current/userguide/jacoco_plugin.html#sec:jacoco_tasks
也许对于早期版本的gradle，您需要添加jacoco依赖项：
...
dependencies {
сlasspath (
[group: 'org.jacoco', name: 'org.jacoco.agent', version: version: '0.7.7.201606060606'],
[group: 'org.jacoco', name: 'org.jacoco.ant', version: version: '0.7.7.201606060606']
)}
