Skipping JaCoCo execution due to missing execution data file

[joel.cos...@gmail.com]

Hi,

I'm the lead developer of AssertJ Core and I could use a bit of help trying to identify why jacoco is missing the execution data file.

It is likely something misconfigured but I can't put my finger on it.

You should be able to reproduce the issue by cloning https://github.com/joel-costigliola/assertj-core and executing

mvn clean jacoco:prepare-agent package jacoco:report -Dtest=StandardRepresentation_toStringOf_Test

(you can execute all the tests but there are more than 1000 so executing just one is way quicker).

I have verified that I was surefire plugin was configured with forkCount = 1 (so not 0).

The build run jacoco prepare-agent which outputs

[INFO] argLine set to -javaagent:/home/joel/.m2/repository/org/jacoco/org.jacoco.agent/0.8.5/org.jacoco.agent-0.8.5-runtime.jar=destfile=/home/joel/prog/assertj/assertj-core-3.x/target/jacoco.exec,excludes=**/*hamcrest*/** --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.util=ALL-UNNAMED
 --add-opens
 java.base/java.io=ALL-UNNAMED --add-opens java.base/java.math=ALL-UNNAMED

I have executed the build in debug and found that surefire argline did not show jacoco destfile setting, I'm not sure if that's a problem ...

argLine = --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.util=ALL-UNNAMED
          --add-opens
          java.base/java.io=ALL-UNNAMED --add-opens java.base/java.math=ALL-UNNAMED

My environment looks like:

Maven home: /home/joel/prog/apache-maven-3.5.3
Java version: 11.0.2, vendor: Oracle Corporation
Java home: /home/joel/.sdkman/candidates/java/11.0.2-open
Default locale: en_NZ, platform encoding: UTF-8
OS name: "linux", version: "4.4.0-169-generic", arch: "amd64", family: "unix"

Any help  would be welcome as I'm running out of ideas.

Cheers

we found a workaround by removing the argLine settings in the java 9 maven profile, we are still not sure why this overrding the jacoco arg.

since assertj-core development continues, I have created a jacoco branch to reproduce the issue (don't use master branch anymore).

Hi Joel,

You have following configuration of maven-surefire-plugin ( https://github.com/joel-costigliola/assertj-core/blob/e5bdf79013895ffa3f94b090d4598912c4fccd42/pom.xml#L230-L235 )

<plugin>

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

  <configuration>

    <argLine>${argLine}</argLine>

  </configuration>

</plugin>

whereas according to documentation of jacoco-maven-plugin goal prepare-agent ( https://www.jacoco.org/jacoco/trunk/doc/prepare-agent-mojo.html )

either argLine should be specified only as a property and not in configuration,

or syntax for late property evaluation ( http://maven.apache.org/surefire/maven-surefire-plugin/faq.html#late-property-evaluation ) should be used.

Removal of argLine from configuration won't work, because it is also specified in parent pom ( https://github.com/joel-costigliola/assertj-maven-parent-pom/blob/assertj-parent-pom-2.2.6/pom.xml#L376 ) and therefore will be inherited - you can check this using help:effective-pom

According to my experiments for your project, use of late property evaluation works perfectly:

<plugin>

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

  <configuration>

    <argLine>@{argLine}</argLine>

  </configuration>

</plugin>

BTW nice to see that AssertJ uses JaCoCo! I added it to page https://github.com/jacoco/jacoco/wiki/Projects-that-use-JaCoCo

Regards,

Evgeny

Thanks Evgeny for the help! We will use <argLine>@{argLine}</argLine>  as you suggested.

Cheers
