Odd Question, but is there a copy of 2.2.1 somewhere?

Avid dbFlow user and took over a project that was on 2.x. Spent over a year in down time updating the project in the background to 5.x. Have 1 more release on the 2.x before testing begins on the upgrade. It worked mid month last month, but now won't compile with the pom missing on the 2.x version. Any idea of what might be causing it?
