Skip Jacoco execution conditonally

[edward...@gmail.com]

Hi,

I'm trying to figure out how I can conditionally skip the Jacoco instrumentation and coverage analysis in a Gradle build. I don't want the coverage tasks to run in every execution of the build, I'd like to be able to control that using a command line property. I tried extracting the Jacoco code to its own Gradle file and using apply from: as in https://stackoverflow.com/questions/42501869/gradle-skip-jacoco-during-test, but this results in:

java.lang.ClassNotFoundException: org.jacoco.agent.rt.internal_1f1cc91.PreMain

Any insight on how to accomplish this?

Thanks,
Edward

Hi,

JaCoCo plugin for Gradle is not developed by JaCoCo Team - see https://www.jacoco.org/jacoco/trunk/doc/integrations.html

and there is not much Gradle experts in this mailing list who provide answers,

so I would advice to use another channel for such Gradle-specific questions.

However based on https://docs.gradle.org/current/userguide/jacoco_plugin.html#default_values_of_the_jacoco_task_extension :

for following "build.gradle"

apply plugin: 'java'

apply plugin: 'jacoco'

repositories {

  mavenCentral()

}

dependencies {

  testCompile 'junit:junit:4.12'

}

test {

    jacoco {

        enabled = "$jacocoEnabled".toBoolean()

    }

}

and "src/main/java/Example.java"

class Example {

  void example() {

  }

}

and "src/test/java/ExampleTest.java"

public class ExampleTest {

  @org.junit.Test

  public void test() {

    new Example().example();

  }

}

execution of

gradle --info clean build -PjacocoEnabled=true

shows that JaCoCo Java Agent is used during execution of tests ( "java ... -javaagent:.../jacocoagent.jar ..." )

and file "build/jacoco/test.exec" is produced,

while execution of

gradle --info clean build -PjacocoEnabled=false

shows that agent is not used and file is not produced.

And the same in case of following "build.gradle"

apply plugin: 'java'

repositories {

  mavenCentral()

}

dependencies {

  testCompile 'junit:junit:4.12'

}

if ("$jacocoEnabled".toBoolean()) {

  apply plugin: 'jacoco'

}

Hope this helps.
