Jenkins and Ant not playing nicely with Jacoco

Question

When building the project with Ant directly I get a coverage report from Jacoco as expected, the .exec file is created and the corresponding reports directory is created in the test/reports directory. When building the project through Jenkins the jacoco.exec file is created but is empty and the actual reports directory is missing. I have tried various path configurations on the Jenkins side thus far without any luck, I am assuming this is some failure of interaction between Jenkins and Ant as the Jacoco plugin for Jenkins simply collects the coverage report output from the build and displays it. I simply want to get a coverage reading on our Jenkins builds, has anyone been down this road? Thank you in advance for any and all assistance/advice.

Edit

Welcome to stackoverflow. It would be helpful to include your code. — Mark O'Connor
@MarkO'Connor an excellent point, forgive me apparently having a dull moment. Edited to include build file. — Samu
This has been solved, you must be careful with the 'includes' and excludes' clauses within the Jacoco target, if the syntax isn't quite right it will include nothing and subsequently show 0% coverage across all classes. — Samu
