When I run the ant task using 'ant hsqldb', my compiled class versions are all 51.0 (Java 7).
I don't understand the documentation at http://hsqldb.org/doc/guide/building-app.html. It sounds like all I should need to do is this:
However, that seems to have no effect - compiled class versions are still 51.0. I'm on a Mac, which does not have Java 1.5, so I'm expecting that the compiler will use -source 1.5 -target 1.5. Is that not how the build task works?
The Java 1.5 builds are for JDK 1.5. We have not tried to build them with JDK 7 and it probably won't work.
