我想要的是：
我想在Android gradle中将代码覆盖率阈值与最小值匹配，如60％等。
我试过的
stack overflow question i have looked into
我面临的问题
我的Gradle文件写成：
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，我面临以下错误
无法在类型为org.gradle.api.Project的项目'：app'上找到参数[build_5t0t9b9hth6zfihsyl5q2obv8 $ _run_closure2 @ 41a69b20]的方法jacocoTestReport（）。
如果我评论jacocoTestReport任务然后
无法在类型为org.gradle.api.Project的项目'：app'上找到参数[build_5t0t9b9hth6zfihsyl5q2obv8 $ _run_closure2 @ 3da790a8]的方法jacocoTestCoverageVerification（）。
我无法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。
gradle是从android插件中选择jacoco插件吗？
我已经尝试过将jacoco的版本提到0.6.3，正如文档中提到的那样，jacocoTestCoverageVerification方法是在这个版本之上编写的。
如果有人能解决这个问题，那将会非常有帮助。
请告诉我所需的任何其他信息。
谢谢
首先检查gradle版本：对于同样应用Java插件的项目，JaCoCo插件会自动添加以下任务：
gradle 3.3（jacocoTestReport任务）https://docs.gradle.org/3.3/userguide/jacoco_plugin.html#sec:jacoco_tasks
gradle 3.5（jacocoTestReport，jacocoTestCoverage验证任务）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']
)}
...
每次关键字android jacocoTestCoverageVerification引导我到这个页面并且没有得到答案时，这个问题一直困扰着我几次。最后，我成功地完成了jacoco工作，我想在这里分享我的解决方案。
gradle无法找到jacocoTestCoverageVerification和jacocoTestReport的原因是因为For projects that also apply the Java Plugin, the JaCoCo plugin automatically adds the following tasks jacocoTestReport and jacocoTestCoverageVerification。这意味着对于不应用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。
按照链接：Code Coverage for Android Testing，我们可以添加任务jacocoTestReport。
同样，我们也可以添加任务jacocoTestCoverageVerification。
