Gradle Jacoco - Could not find method jacocoTestReport ()
I am trying to generate a Jacoco test report in Gradle. When I try to sync my code, I get the following error:
Error: (56, 0) Could not find jacocoTestReport () method for arguments [build_38ehqsoyd54r3n1gzrop303so $ _run_closure4 @ 10012308] in project ': app' of type org.gradle.api.Project.
My build.gradle file contains the following items:
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 can't see anything I am doing wrong.
Gradle version: 3.3
Why am I getting this error and how can I fix it?

Basically I know two ways to achieve this.
The first approach is the built-in function of the android gradle plugin:
android {
...
buildTypes {
debug {
testCoverageEnabled = true
}
...
}
...
}
This will define the gradle tasks that can be done. As far as I know, this works great with instrumental tests. More information: Code wrapper on Android
The second approach is to use this plugin:
https://github.com/vanniktech/gradle-android-junit-jacoco-plugin
The setup is simple:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.6.0'
}
}
apply plugin: 'com.vanniktech.android.junit.jacoco'
And after synchronizing the project, you will have tasks like jacocoTestReport<Flavor><BuildType>
We use this to measure the code coverage of our unit tests running on the local machine.

As stated in the 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.
which is quite logical - measuring the coverage for Java code requires compiling it, running tests, etc.
So using your example build.gradle
causes a crash that goes away after adding apply plugin: 'java'
.
