gradle jacocoTestReport is not working?

Question

I have tried to get code coverage in a spring-gradle project using gradle jacoco plugin.

The build.gradle contains the following

apply plugin: "jacoco"      jacoco {         toolVersion = "0.7.1.201405082137"         reportsDir = file("$buildDir/customJacocoReportDir")     }      jacocoTestReport {     reports {         xml.enabled false         csv.enabled false         html.destination "${buildDir}/jacocoHtml"     } } 

I then ran

gradle test jacocoTestReport 

Where after only the file test.exec is generated in build/reports folder.

Other than that nothing happens.

How can I get the HTML report?

Answer 1

You don't have to configure reportsDir/destinationFile

Because jacoco has default values for them.

build.gradle:

plugins {     id 'java'     id 'jacoco' }  jacocoTestReport {     reports {         xml.enabled true         html.enabled true         csv.enabled true     } }  repositories {     jcenter() }  dependencies {     testCompile group: 'junit', name: 'junit', version: '4.12' } 

Run gradle test jacocoTestReport

You can find the test report in ./build/reports/jacoco/test directory.

HTML output is in ./build/reports/jacoco/test/html directory.

Following helped . its in samples/testing/jacaco of gradle-2.3-all.zip from https://gradle.org/releases/

apply plugin: "java"  apply plugin: "jacoco"  jacoco {     toolVersion = "0.7.1.201405082137"     reportsDir = file("$buildDir/customJacocoReportDir") }  repositories {     mavenCentral() }  dependencies {     testCompile "junit:junit:4.+" }  test {     jacoco {         append = false         destinationFile = file("$buildDir/jacoco/jacocoTest.exec")         classDumpFile = file("$buildDir/jacoco/classpathdumps")     } }   jacocoTestReport {     reports {         xml.enabled false         csv.enabled false         html.destination "${buildDir}/jacocoHtml"     } }
