The problem seems to be an exact replica of this bug for ant sql exec:
https://issues.apache.org/bugzilla/show_bug.cgi?id=36265
I made a local patch of Maven Sql plugin using the fix in the ant sql bug 
report and this solved the problem.
(The patch conforms to my local coding standards so unfortunately has lots of 
trivial changes. You may prefer to make the change directly to the code 
yourselves)
