Just an addition to the answers already given. It could happen that in your maven-surefire-plugin configuration you already use the argLine configuration to override something like the memory used. If you do so the argline set by jacoco-maven-plugin will not be used failing to generate the jacoco report. In this case assign a property name … Read more

The feature is now available. You simply need to apply the Gradle JaCoCo plugin and define coverage verification like this: apply plugin: ‘jacoco’ jacocoTestCoverageVerification { violationRules { rule { limit { minimum = 0.7 } } } } // to run coverage verification during the build (and fail when appropriate) check.dependsOn jacocoTestCoverageVerification The last line … Read more
I found the solution – The maven plugin I have included has configuration of Jacoco’s destfile and datafile as ${basedir}/target/coverage-reports/jacoco-unit.exec but by default sonar reads at ${basedir}/target/jacoco.exec. I changed the default at http://localhost:9000/settings?category=java Ref: Sonar Code Coverage Couldn’t find the working reference link. Here is aux link: Baeldung Sonar and jacoco
Here is how I’m using Jacoco: buildscript { repositories { mavenLocal() mavenCentral() } dependencies { classpath ‘com.android.tools.build:gradle:0.12.+’ classpath ‘org.robolectric:robolectric-gradle-plugin:0.11.+’ } } apply plugin: ‘com.android.application’ apply plugin: ‘robolectric’ apply plugin: ‘jacoco’ android { compileSdkVersion 20 buildToolsVersion “20.0.0” defaultConfig { applicationId “YOUR_PACKAGE_NAME” minSdkVersion 10 targetSdkVersion 20 testHandleProfiling true testFunctionalTest true } buildTypes { debug { testCoverageEnabled false … Read more
You are getting the error related to classID. This is a concept described in detail at JaCoCo docs-site. http://www.eclemma.org/jacoco/trunk/doc/classids.html. This is a key step for supporting multiple versions of class (an appserver for example) in same JVM. Copying part some part of it here for visibility. What are class ids and how are they created? … Read more
JaCoCo version 0.7.7 can generate an aggregate coverage report from multiple Maven modules through a new goal jacoco:report-aggregate.
You can get line-by-line coverage for both Java and Kotlin code by defining the two different directories for generated .class files: def debugTree = fileTree(dir: “${buildDir}/intermediates/classes/debug”, excludes: fileFilter) def kotlinDebugTree = fileTree(dir: “${buildDir}/tmp/kotlin-classes/debug”, excludes: fileFilter) Then, simply include both fileTrees in your classDirectories: classDirectories.from = files([debugTree], [kotlinDebugTree])
Found the solution. I have installed the coverage plugin and the EclEmma plugin (not sure if this one is really necessary…). Then “Run -> Show Coverage Data…” and pick your Jacoco output file. This file HAS to have the .exec extension, otherwise you can’t select it. That was my problem… Thanks
