问题
I'm new to Gradle and Android testing but I've already converted my Android project to build with Gradle.
Now I'm trying to perform test coverage of an Android project with Gradle's JaCoCo plugin.
I've added the following to my build.gradle file:
apply plugin: 'jacoco'
And when I run "gradle jacocoTestReport" the following error:
Task 'jacocoTestReport' not found in root project '<project name>'.
From the documentation I'm supposed to also apply plugin 'java' but it conflicts with plugin 'android'.
Is there a way around this?
Thanks in advance.

Here is how I'm using Jacoco:

mavenLocal()
mavenCentral()
}

classpath 'org.robolectric:robolectric-gradle-plugin:0.11.+'
}
}
apply plugin: 'com.android.application'
apply plugin: 'robolectric'
apply plugin: 'jacoco'
android {

buildToolsVersion "20.0.0"
defaultConfig {
applicationId "YOUR_PACKAGE_NAME"
minSdkVersion 10

testHandleProfiling true
testFunctionalTest true
}
buildTypes {

testCoverageEnabled false
}
release {

// Define coverage source.

def coverageSourceDirs = [

}

excludes: ['**/R*.class',

// Bit hacky but fixes https://code.google.com/p/android/issues/detail?id=69174.

doFirst {

if (file.name.contains('$$')) {
file.renameTo(file.path.replace('$$', '$'))
}
}
}
}
dependencies {
androidTestCompile('junit:junit:4.11') {
exclude module: 'hamcrest-core'
}
androidTestCompile('org.robolectric:robolectric:2.3') {
exclude module: 'classworlds'

}
The above code also contains a workaround for https://code.google.com/p/android/issues/detail?id=69174.

I'm using JaCoCo with a project using RoboGuice, Butterknife and Robolectric. I was able to set it up using @Hieu Rocker's solution, however there were some minor drawbacks i.e. in our project we use flavors and have some extra tests for those flavors as well as extra java code for each of them. We also use different build types. Therefore a solution to rely on the "testDebug" task was not good enough. Here's my solution: In build.gradle in app module add
apply from: '../app/jacoco.gradle'
Then create a jacoco.gradle file inside of app module with the following content:
apply plugin: 'jacoco'
jacoco {
toolVersion "0.7.1.201405082137"
}
def getFlavorFromVariant(String variantName) {
def flavorString = variantName.replaceAll(/(.*)([A-Z].*)/) { all, flavorName, buildTypeName ->
flavorName
}
return flavorString;
}
def getBuildTypeFromVariant(String variantName) {
def buildTypeString = variantName.replaceAll(/(.*)([A-Z].*)/) { all, flavorName, buildTypeName ->
"${buildTypeName.toLowerCase()}"
}
return buildTypeString;
}
def getFullTestTaskName(String variantName) {
return "test${variantName.capitalize()}UnitTest";
}
android.applicationVariants.all { variant ->
def variantName = variant.name;
def flavorFromVariant = getFlavorFromVariant("${variantName}");
def buildTypeFromVariant = getBuildTypeFromVariant("${variantName}");
def testTaskName = getFullTestTaskName("${variantName}")
task ("jacoco${variantName.capitalize()}TestReport", type: JacocoReport, dependsOn: testTaskName) {
group = "Reporting"
description = "Generate JaCoCo coverage reports after running tests for variant: ${variantName}."
reports {
xml.enabled = true
html.enabled = true
}
classDirectories = fileTree(
dir: "./build/intermediates/classes/${flavorFromVariant}/${buildTypeFromVariant}",
excludes: ['**/R*.class',
'**/*$InjectAdapter.class',
'**/*$ModuleAdapter.class',
'**/*$ViewInjector*.class'
]
)
logger.info("Configuring JaCoCo for flavor: ${flavorFromVariant}, buildType: ${buildTypeFromVariant}, task: ${testTaskName}");
def coverageSourceDirs = [
'../app/src/main/java',
"../app/src/${flavorFromVariant}/java"
]
sourceDirectories = files(coverageSourceDirs)
executionData = files("$buildDir/jacoco/${testTaskName}.exec")
// Bit hacky but fixes https://code.google.com/p/android/issues/detail?id=69174.
// We iterate through the compiled .class tree and rename $$ to $.
doFirst {
new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
if (file.name.contains('$$')) {
file.renameTo(file.path.replace('$$', '$'))
}
}
}
}
}
You can execute it from command line like this:
.gradlew jacocoFlavor1DebugTestReport
or
.gradlew jacocoOtherflavorPrereleaseTestReport
In our project we use a convention not to use capital letter inside of flavor and build type names, but if your project does not follow this convention you can simply change getFlavorFromVariant(..) and getBuildTypeFromVariant(..) functions
Hope this helps someone

You can try to use this Gradle plugin: https://github.com/arturdm/jacoco-android-gradle-plugin
There's a bit more in the answer here https://stackoverflow.com/a/32572259/1711454.

Did you try adding the following:
jacocoTestReport {
group = "Reporting"
description = "Generate Jacoco coverage reports after running tests."
additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
}
And then instead of running ./gradlew jacocoTestReport run ./gradlew test jacocoTestReport.
If all goes well you should find the test results at build/reports/jacoco/test/html/index.html.
