Andrew McIntyre commented on DERBY-1526:
----------------------------------------
The only information expected to be in ${user.home}/ant.properties for the
Derby build is the location of the runtime java libraries that are accessible
to the current user. These runtime classes can (and should) be static across
Derby versions. i.e. the versions of Java that you use to build any particular
version of Derby should consistently build multiple versions of Derby. There
shouldn't be any information in ${user.home}/ant.properties that is specific to
a specific version of Derby.
With the current setup, I can specify the locations of the multiple versions of
the runtime classes needed to build Derby once for each machine/user where I am
building in the user's ant.properties. Then, I can build 10.0, 10.1, and 10.2
without needing to change anything but the directory where I've checked out the
source. The requirements on Mac OS X for the content in ant.properties is
somewhat different, as noted in BUILDING.txt, but once set up, I can build
Derby 10.0, 10.1, and the trunk without needing to set up a separate properties
file for each individual checkout of the source. I find this very handy.
That said, I can understand the desire not to introduce a dependency on a
user-space file. I think there is room for improvement here if we also sourced
a file from ${basedir} in addition to the user.home, in case a user wants to
have these base properties sourced from a file that is specific to a particular
checkout of Derby.
As far as the affects version, there currently is not a way to track specific
Subversion revisions in JIRA. Since it looks like you are working with the
trunk, we are tracking the current trunk version as 10.2.0.0 in JIRA. For the
other versions, the latest released 10.1 version is 10.1.3.1 and the latest
released 10.0 version is 10.0.2.1.

> I think it is problemmatic that the Derby build process makes use of, for
> example, ${user.home}/ant.properties.
> I would actually like to be able to build multiple versions of Derby. I also
> cannot see what is gained by relying on the user's home directory in this
> manner. All of this information could be put into a configuration that can be
> kept in the project directory. That would work just fine.
> By the way, I am looking at the top-of-tree code. How do I refer to that in
> the "Affects Version" box above? This version is 422938.
