Thanks a lot; this is what I was looking for.
However, there is a minor problem for my use case. I need to be able
to specify an absolute filename as the antfile attribute. This means
every subproject uses the same (given) antfile. In my case this will
be the ${ant.file} of the superproject. All subproject specific
settings are specified in a property file within the subproject's
'build' subfolder.
To be able to handle this with <subant> (and <ant>), without copying
my antfile around, i need to patch the following:
- SubAnt.execute() and SubAnt.execute(file): the current code uses
Ant.setAntfile to implicitly set the basedir of the subproject. I
need to this explicitly by using the Ant.setDir method. I want to
use java.io.File.isAbsolute() to distinguish between absolute and
relative antfile values. I need to change the SubAnt.execute(File)
interface to SubAnt.execute(File dir, String antfile). If antfile
is a relative name the handling keeps as it is, if it is absolute,
it is given to Ant.setAntfile unchanged.
- Ant.execute: my current ant version (1.5.1 as packaged on Debian)
just uses FileUtils.resolveFile to combine the basedir and the name
of the antfile unconditionally. I would change that to only combine
them if java.io.File.isAbsolute(antFile) returns false. Otherwise
I'd leave antFile as it is.
As you can see this would be no big deal. Before I actually do it I
would like to ask some questions (not only to you Dominique but also
to others):
- Would you consider such a 'feature' for SubAnt to be useful? Would
the ant maintainers consider it to be useful for the Ant-task? If I
understand FileUtils.resolveFile correctly, no existing antfiles
should be broken by this change. But please note that I'm very new
to ant.
- Should I send a patch to this list or should I use the bugtracking
system?
- Against which ant version should I create a patch? Please note that
I have no access to cvs (firewall issue).
TIA,
andreas
