@jjjimenez100 the build is failing due to PMD error. See https://travis-ci.org/iluwatar/java-design-patterns/builds/594261640

Hi @iluwatar. Sorry about that, this is actually my first PR with a repo having checkstyle and PMD.
I tried running mvn pmd:pmd pmd:cpd on the pipeline directory I did to try and correct errors it reported. Hopefully this will have a successful build now 👌

Thanks @jjjimenez100, beautiful pattern and well implemented 👍

I don't know if this is related, but the pipeline project is failing to compile for me because of the project hierarchy.

It's currently:

src/main/java/com.iluwatar.pipeline/*.java

I think it should be:
src/main/java/com/iluwatar/pipeline/*.java

Also I have a commit that I can push up as a PR.

@oconnelc please create an issue about the problem, and then the PR that fixes this
