Gradle Jacoco - Could not find method jacocoTestReport()
提问by Guido
I'm trying to generate a Jacoco test report in Gradle. When I try to sync my code, I will receive the following error:
我正在尝试在 Gradle 中生成 Jacoco 测试报告。当我尝试同步我的代码时,我会收到以下错误:
Error:(56, 0) Could not find method jacocoTestReport() for arguments [build_38ehqsoyd54r3n1gzrop303so$_run_closure4@10012308] on project ':app' of type org.gradle.api.Project.
错误:(56, 0) 无法在 org.gradle.api.Project 类型的项目“:app”上找到参数 [build_38ehqsoyd54r3n1gzrop303so$_run_closure4@10012308] 的方法 jacocoTestReport()。
My build.gradle file contains the following items:
我的 build.gradle 文件包含以下项目:
apply plugin: 'jacoco'
jacoco {
toolVersion = "0.7.6.201602180812"
reportsDir = file("$buildDir/reports/jacoco")
}
jacocoTestReport {
group = "Reporting"
reports {
xml.enabled true
csv.enabled false
html.destination "${buildDir}/reports/coverage"
}
}
When I look at the documentation , I don't see anything which I'm doing wrong.
当我查看文档时,我没有看到任何我做错的地方。
Gradle version: 3.3
摇篮版本:3.3
Why am I receiving this error and how can I fix it?
为什么我会收到此错误,我该如何解决?

Basically I know two ways to achieve this.
基本上我知道两种方法来实现这一目标。
The first approach is the built-in android gradle plugin feature:
第一种方法是内置的android gradle插件功能:
android {
...
buildTypes {
debug {
testCoverageEnabled = true
}
...
}
...
}
This one will define gradle tasks, which can be executed. As far as I know this works fine with instrumentation tests. More information: Code Coverage on Android
这将定义可以执行的 gradle 任务。据我所知,这适用于仪器测试。更多信息:Android 上的代码覆盖率
The 2nd approach is to use this plugin:
第二种方法是使用这个插件:
https://github.com/vanniktech/gradle-android-junit-jacoco-plugin
https://github.com/vanniktech/gradle-android-junit-jacoco-plugin
Setup is easy:
设置很简单:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.6.0'
}
}
apply plugin: 'com.vanniktech.android.junit.jacoco'
And after project sync, you will have tasks like jacocoTestReport<Flavor><BuildType>
项目同步后,您将有类似的任务 jacocoTestReport<Flavor><BuildType>
We use this to measure the code coverage of our unit tests running on the local machine.
我们用它来衡量在本地机器上运行的单元测试的代码覆盖率。

As stated in documentation mentioned in your question:
If the Java plugin is also applied to your project, a new task named jacocoTestReport is created that depends on the test task.
如果 Java 插件也应用于您的项目,则会创建一个名为 jacocoTestReport 的新任务,该任务依赖于测试任务。
what is pretty logical - measurement of coverage for Java code requires its compilation, execution of tests, etc.
什么是合乎逻辑的 - 测量 Java 代码的覆盖率需要编译、执行测试等。
So that indeed usage of your example of build.gradle
causes failure, which disappears after addition of apply plugin: 'java'
.
因此,确实使用您的示例build.gradle
导致失败,添加apply plugin: 'java'
.
