Description of Problem
Using ant HibernateToolTask to generate ddl using hbm2ddl. This task is located in ./inner/build.xml.
Problem is that when ant build files are chained together, i.e. ./outer/build.xml calls ./inner/build.xml, the ddl output is written to a directory relative to ./outer, not ./inner as is specified by the "destdir" attribute in the ant task.
I'm attaching both the inner and outer build.xml's as well as the output from running them. I've added echo statements to show that the value of "destdir" is identical whether run from inner or outer.
Any help appreciated! This is causing us to write lots of hacky build deployment code as our build scripts are chained.
My only other suspect is HSQLDB is causing this, but the connection url in hibernate.properties is pointing to dir 'junk' and that is apparently not being used in either case (inner or outer).
Thanks,
Michael
