Hi @aterrel I saw this last night as well, however I cannot reproduce with master branch. After checking out a fresh copy of the codebase and following the instructions in the README, I get a clean, successful build

Additionally, I would comment that the proposed fix posted by Shadi Saleh suggests that the source and target Javac should be pinned to 1.5, this is not correct. The README for Nutchpy explicitly states JDK1.6+, meaning that at a minimum the maven-compiler-plugin config, if included, should be pinned to 1.6.

I don't see anything wrong with Nutchpy as it stands. It would be very useful to see someone else make an attempt to install from scratch. Thanks

I think this isn't an error anymore.
