我想要什么:
我想在 Android gradle 中将代码覆盖率阈值匹配到最小值，如 60% 等。
我尝试过的
stack overflow question i have looked into
jacoco plugin gradle
我面临的问题
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，我面临以下错误
在 org.gradle.api.Project 类型的项目“:app”上找不到参数 [build_5t0t9b9hth6zfihsyl5q2obv8$_run_closure2@41a69b20] 的方法 jacocoTestReport()。
如果我评论 jacocoTestReport 任务，那么
在 org.gradle.api.Project 类型的项目“:app”上找不到参数 [build_5t0t9b9hth6zfihsyl5q2obv8$_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 是不是从 android 插件中选择了 jacoco 插件？
我已经尝试将 jacoco 的版本提到 0.6.3，正如那里的文档中提到的 jacocoTestCoverageVerification 方法写在这个版本之上。
如果有人能解决这个问题，那将非常有帮助。
让我知道任何其他需要的信息。
谢谢
最佳答案
这个问题一直困扰着我几次，每次关键字 android jacocoTestCoverageVerification 将我带到这个页面并且没有得到任何答案。最后，我成功地使 jacoco 工作，我想在这里分享我的解决方案。
gradle 找不到 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 Plugin 的项目， 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。
和 一样，我们也可以添加任务 jacocoTestCoverageVerification。

final capVariant = variant.capitalize()
StringBuilder folderSb = new StringBuilder(variant.length() + 1)

char c = variant.charAt(i)
if (Character.isUpperCase(c)) {
folderSb.append('/')
folderSb.append(Character.toLowerCase(c))

folderSb.append(c)
