jacoco.exec file is not generated after running jacoco maven 'prepare-agent' goal

[Nihar Kurapati]

Hi,

I couldn't see any jacoco.exec file generated in 'target' folder after running "mvn jacoco:prepare-agent", but the build is success and during the build process I see message like below

"[INFO] argLine set to -javaagent:E:\workdir\unit\out\repository\org\jacoco\org.jacoco

.agent\0.6.3.201306030806\org.jacoco.agent-0.6.3.201306030806-runtime.jar=destfile=E:\workdir\unit\src\<project>\src\<package>\target\jacoco.exec"

But when I check at the location after the build is success, I don't see any .exec file in the specified location. 

Please help me out on resolving this issue. For reference please see my pom.xml below and I'm using GwtMockito for unit tests.

Hi,

how do you start / run your unit tests?
Do you have any configuration for maven-surefire-plugin, for example something like <argLine>-XmX1024M</argLine>?

Do the tests run in the same VM you are attaching the jacoco agent to, or does the actual code run in a different VM?

regards,

Henrik

Hi,

Thanks for your quick response. 

I usually run unit tests using mvn test command.

Please see below how is maven-surefire-plugin configured in pom.xml

<plugin>

      <groupId>org.apache.maven.plugins</groupId>

      <artifactId>maven-surefire-plugin</artifactId>

      <version>2.16</version>

      <dependencies>

          <dependency>

              <groupId>org.apache.maven.surefire</groupId>

              <artifactId>surefire-junit47</artifactId>

              <version>2.16</version>

          </dependency>

      </dependencies>

      <configuration>

          <argLine>-Xmx1024M</argLine>

      </configuration>

</plugin>

I'm not exactly sure, whether the tests run in the same VM or different VM. Please let me know how can I check that.

Thanks,

Nihar

[Marc Hoffmann]

Hi Nihar,

so you're overwriting the argLine property again. Try this one:

<argLine>-Xmx1024M ${argLine}</argLine>

Cheers,

Thanks for your response Marc.

I tried what you've suggested and it fails the build now with below error.

Error: Could not find or load main class ${argLine}

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.16:test (default-tes

t) on project <projectName>: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin

 called ?

Thanks,

Nihar

[Marc Hoffmann]

This is strange. If you check the build log: Has the argLine property
been set *before* the test execution?

I don't think it is set before test execution. what it should be set to?

Thanks,

Nihar

[Henrik Horneber]

It gets set by jacoco. Your first mail contained the actual line.

It's hard to tell what is going on without seeing the complete pom.

Here is how my complete pom looks like.

Hi,

It generates jacoco.exec file when I specify the java agent explicitly in surefire's <argLine> attribute, please see below

<plugin>

      <groupId>org.apache.maven.plugins</groupId>

      <artifactId>maven-surefire-plugin</artifactId>

      <version>2.16</version>

      <dependencies>

          <dependency>

              <groupId>org.apache.maven.surefire</groupId>

              <artifactId>surefire-junit47</artifactId>

              <version>2.16</version>

          </dependency>

      </dependencies>

      <configuration>

          <argLine>-javaagent:${settings.localRepository}/org/jacoco/org.jacoco.agent/0.6.3.201306030806/org.jacoco.agent-0.6.3.201306030806-runtime.jar=destfile=${project.build.directory}\jacoco.exec</argLine>

      </configuration>

</plugin>

It seems like my problem is similar to the one posted in https://groups.google.com/forum/#!msg/jenkins-jacoco-plugin-mailing-list/4SwvdUwLNAg/ZzCrqQAD0nsJ. So, there is no other way to fix this problem?

In my case I'm  using GwtMockito (Mocking framework), not sure whether the above post applies to all mocking frameworks.

Please help me out. Appreciate your help.

Thanks,

Nihar

Hi,

as I am not at work right not I can' tell for certain, but I'm pretty sure that your pom is exactly what my working ones look like, except for the argLine property.

Like this:

<!--- CHANGED HERE from what you sent -->

          <argLine>-Xmx1024M ${argLine}</argLine>

      </configuration>

</plugin>

... but you already tried that, since this is what Marc suggested, right?

Someone else recently sent an example on how to configure jacoco so it does not set argLine but a different property, using propertyName.

Ah, here https://groups.google.com/forum/#!topic/jacoco/09if-cdReGQ.

Might be worth another shot.

[Nihar Kurapati]

Hi,

Sorry for late reply. I've tried with propertyName also, still doesn't work. It only works when I explicitly mention java agent, and with this configuration rules doesn't seem like working.

Appreciate your help.

Thanks,

Nihar

[Nihar Kurapati]

FYI

I solved the issue without setting the java agent explicitly in surefire <argLine> tag. i.e.

Previously I've my jacoco plugin embedded inside pluginManagement tag, when moving it out of pluginManagement and keeping it inside plugins tag of maven it worked as expected with 'propertyName' approach :)

So, here is how my working pom looks like

<plugins>

    <plugin>

        <groupId>org.jacoco</groupId>

        <artifactId>jacoco-maven-plugin</artifactId>

        <version>${jaCoCoVersion}</version>

        <configuration>

         <dataFile>${jaCoCoExecutionDataFile}</dataFile>

        </configuration>

        <executions>

            <execution>

             <id>jacoco-initialize</id>

                   <phase>initialize</phase>

     <goals>

   <goal>prepare-agent</goal>

   </goals>

   <configuration>

                      <propertyName>jacoco.agent.argLine</propertyName>

                      <destFile>${jaCoCoExecutionDataFile}</destFile>

 </configuration>

</execution>

<execution>

 <id>jacoco-report</id>

   <phase>verify</phase>

   <goals>

   <goal>report</goal>

   </goals>

   </execution>

  </executions>

      </plugin>

</plugins>

<pluginManagement>

    <plugins>

        <plugin>          

          <groupId>org.apache.maven.plugins</groupId>

          <artifactId>maven-surefire-plugin</artifactId>

          <version>2.16</version>

          <dependencies>

            <dependency>

              <groupId>org.apache.maven.surefire</groupId>

              <artifactId>surefire-junit47</artifactId>

              <version>2.16</version>

            </dependency>

          </dependencies>

          <configuration>            

<argLine>${jacoco.agent.argLine}</argLine>

          </configuration>

        </plugin>

      </plugins>

</pluginManagement>

Thanks a lot for your help.

Hi There,

i have to generate the test coverage report for integration testing ,but while using jacoco i am getting below error

Skipping JaCoCo execution due to missing execution data file

i have a server code project in which i have written some services and another project in which i have written the integration test cases.so my integration test cases are hitting server code services and executing fine not able to generate the test coverage report as getting above error.

my doubt is  : how to  jacoco prepare agent get to know  for loading the classes from server project.

Please find attached pom.xml file

Thanks and regards,

Vijay Singh

​

 jacoco.txt

​​

 pom.xml

​

could you write me the content to be mentioned in the pom file for capturing the test report code coverage...

 we have project which is having test cases for services deployed on the local tomcat or remote tomcat server(war file deployed on tomcat) so when i will execute the test cases these will hit the services and validates the test cases.

​

 SampleExample.zip

​​

 RESTfulExample.zip

​

i am able to get the jacoco.exec file in the target folder of SampleExample project but site folder is not get created

Thanks and regards,

jacoco:report goal should be executed in order to generate report ( http://eclemma.org/jacoco/trunk/doc/report-mojo.html ), which is not happening according to your log, because it is not presented in your pom.xml

how do we get the report for the code files which are not in the same project from where we are executing the jacoco goals...like in case of integration test cases which are hitting the REST services deployed on the remote tomcat server..
