@alansaid: Thank you for you answer.
Even though travis might not fail due to javadoc errors, mvn install should. This is a decision made in order to guarantee that JavaDocs stay up to date
I have this doubt simply because I think that if someone which contributes to the RiVal project doesn't use
mvn install, he may introduce some JavaDoc errors . In my opinion can be useful to execute the same command on Travis too in order to prevent this kind of errors. What do you think about that? Am I saying something wrong?
