A developer of my company was promoted to a new possition that practically manages us developers, and he assigned to 3 people in our team(including me) some big proyects done in Java/Delphi/.NET, the point of being a team was so that each of us could manage each other's code in case that someone goes on vacation or leaves the company for any reason.
Suggestions start on monday but i really have not found any solid information on how language agnostic teams work, nor how to manage one, although my idea was to advice a eclipse/maven/jenkins enviroment with TDD approach for java projects, but i do not know what is best for us in the other languages.
Would you migrate the Delphi .Net applications to Java as well? Or would you learn both languages as well and just leave it as it is.
I am sort of a java fanboy but i wouldn't mind learning other languages, but what i do think is that having one language has advantages like everyone knowing the same tools and less tools to master.
I still do not know what to suggest besides what i said above, any advice on this sort of problems is appreciated.
