Migration questions for Play 1.2.4 project

I’ve been asked to analyze (with SonarQube,) a project developed with Play 1.2.4, and I’m trying to make a virtual environment (docker image) with required dependencies. So far, it looks like Java7, python2 is required. Once play-1.2.6 was installed, I could bring it up, but I seem to need more dependencies. The install instructions specify spring-1.0.3;I tried play install spring-1.0.3 but got a message:

~ Oops,
~ Cannot fetch the modules list from http://www.playframework.org/modules (403)...

I’m wondering if there should be some newer versions available?
