Oliver,

Thanks for the info, so "ant driver" will create Java sources from the "templated files".
How does it know which JDBC version and which JDK version I have the desire to build for?
Is it in some config files or additional command line parameters for the "ant driver" command or some environment variables?

Releasing multiple separate sources for different versions of a product does not confusing me at all.
Having one source code for each target version might be more confusing.
Both ways have its own difficulties and their own benefits, and I am not trying to switch you.

Albert

The slightly misleadingly named target "driver" will configure the build
environment and do all the substitutions, but not actually compile the
result. So: "ant driver"

Because the substitutions that are needed are different depending on
your build environment e.g. which JDBC version and JDK you are building
for. The ant buildfile handles both detecting your build environment and
performing suitable substitutions. Releasing multiple source
distributions, each of which only works for one environment, where the
only difference is in the 3-4 templated files - that'd be confusing and
unnecessary when the build process already handles it, don't you think?

I don't think we really support building the driver except via ant, it
is something of a de-facto standard for building Java these days. (Ok,
now the Maven people are going to yell at me ;-))

Consider it a prerequisite for building the driver, just like having a
functional JDK installed is a prerequisite.
