Unable to see generated test source folder with mojo's build-helper

Question

I have added the mojo's plugin build-helper to my project pom to generate a new test source folder for my integration tests. When I run the phase, generate-test-sources

   mvn generate-test-sources

I could see the below console output showing the test source folder has generated, but When I look in project explorer, I don't see any folder which was created.

            </configuration>
          </execution>
        </executions>
</plugin>

Am I doing something wrong?. Please help.

Thanks

I think I found the answer to my question. I was actually expecting build-helper plugin to create the test folder for me. But the fact is, it won't create the folder for you.

You have to create the test folder and use this build-helper plugin to tell maven to treat the folder you created as test folder as shown in my pom above. I was able fix my issue by creating a new test folder and ran the following command

mvn generate-test-sources eclipse:eclipse

Hope this helps someone!
