Error with Maven building existing Groovy project

Question

I want to reproduce the branch iswc13 from the following github project: https://github.com/linqs/KnowledgeGraphIdentification/tree/master . I clone the project locally and then I switch to the iswc13 branch. My environment is Ubuntu 16.04, Maven 3.3.9 and Openjdk version "1.8.0_121". I need help since I'm getting the following error when I try to compile the project.

Answer 1

It was a Java version issue. The project was done with a previous version of Java and was not working with my current settings, ie,Openjdk version "1.8.0_121". I had to use a pom.xml file made for Java 1.8. I replaced the current one with this and it compiled successfully.
