Not working with org.jacoco:jacoco-maven-plugin

Hi, I just updated a large project from java 11 to 17 and introduced log-captor for unit testing.

Now all my test are fine in the IDE, but when running them in the CI/CD pipeline on the server or locally with “./mvnw org.jacoco:jacoco-maven-plugin:prepare-agent test -Dmaven.test.failure=true”

I face failing tests depending on the environment these are different test. Always the log-captor seems to miss some logging.

This is how the pom looks like:

                    </configuration>
                </plugin>

Any ideas what might go wrong?

Thanks for your help, we need the snapshot package.

I’ll try to test logging with a custom appender.

I just found out that when I used that library, json-snapshot, none of my tests got executed. I could not replicate on my side that LogCaptor was causing issues, but maybe my setup is not identical to yours.

You could also try to use https://github.com/Hakky54/console-captor which just captures the console output. In that way you don’t need a custom appender or custom logic to capture logs from a logging framework.
