Does anybody know how to configure a gradle file for java jacoco report that contain codecoverage of more than one gradle submodule?
my current approach only shows codecoverage of the current submodule but not codecoverage of a sibling-submodul.
I have this project structure
- build.gradle (1)
- corelib/
- build.gradle (2)
- src/main/java/package/Core.java
- extlib/
- build.gradle (3)
- src/main/java/package/Ext.java
- src/test/java/package/Integrationtest.java
when i execute gradlew :extlib:check :extlib:jacocoTestReport
the junit-test "Integrationtest.java"
is executed and a codecoverage report is generated that does not contain codecoverage for corelib classes like Core.java
The result should include the codecoverage of Ext.java and Core.java
I already read
but found no clues
here is content of the gradle files
// root build.gradle (1)
// Top-level build file where you can add configuration options
// common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
}
}
allprojects {
repositories {
jcenter()
}
}
// build.gradle (2) subproject build file for corelib.
apply plugin: 'java'
apply plugin: 'jacoco'
dependencies {
}
jacocoTestReport {
reports {
xml.enabled true
html.enabled true
}
}
// build.gradle (3) subproject build file for extlib.
apply plugin: 'java'
apply plugin: 'jacoco'
dependencies {
compile project(':corelib')
testCompile 'junit:junit:4.11'
// this does not compile
// jacocoTestReport project(':pixymeta-core-lib')
}
jacocoTestReport {
reports {
xml.enabled true
html.enabled true
}
}
// workaround because android-studio does not make the test resources available
// see https://code.google.com/p/android/issues/detail?id=64887#c13
task copyTestResources(type: Copy) {
from sourceSets.test.resources
into sourceSets.test.output.classesDir
}
processTestResources.dependsOn copyTestResources

thanks to @Benjamin Muschko i also tried in the root gradle file
// https://discuss.gradle.org/t/merge-jacoco-coverage-reports-for-multiproject-setups/12100/6
// https://docs.gradle.org/current/dsl/org.gradle.testing.jacoco.tasks.JacocoMerge.html
task jacocoMerge(type: JacocoMerge) {
subprojects.each { subproject ->
executionData subproject.tasks.withType(Test)
}
}
but got error message (with gradle-2.14)
* What went wrong:
Some problems were found with the configuration of task ':jacocoMerge'.
> No value has been specified for property 'jacocoClasspath'.
> No value has been specified for property 'executionData'.
> No value has been specified for property 'destinationFile'.
there is also the gradle plugin https://github.com/paveldudka/JacocoEverywhere where i have asked for mulit-submodule support https://github.com/paveldudka/JacocoEverywhere/issues/16
[update 2016-08-01] i found a working solution based on https://github.com/palantir/gradle-jacoco-coverage
See my own answer below
This works for me
plugins {
id 'org.kordamp.gradle.jacoco' version '0.43.0'
}
config {
coverage {
jacoco {
enabled
aggregateExecFile
aggregateReportHtmlFile
aggregateReportXmlFile
additionalSourceDirs
additionalClassDirs
}
}
}
