That is a recent repository clone, but your contrib components seems to be 
older than the last stable Isabelle release, which has scala-2.9.2 and 
this is also required here.

To make it easier to follow ongoing repository development wrt. contrib 
components, Admin/components has acquired an official status in the past 
few months.

At the end of README_REPOSITORY I have tried to summarize the state of 
affairs with sliding update of Isabelle components, although I would like 
to simplify that further.
