The 'cwd' is never changed. What changes in the project's basedir,
based on the various attributes that <ant> accepts. See the table in
<ant>'s documentation for details.
Personally, I always use <subant> instead of <ant>, to avoid messing
up the 'basedir'. You probably also want to use
p.resolveFile(relative_filename) within your script to translate
relative_filename to an abs. path relative to the project's basedir,
rather than 'cwd', which can be different depending where you call the
build from.
Leaving the 'basedir' alone, combined with p.resolveFile() should do
the trick. --DD

Hey now,
This is my first Ant project (so please bear with me). My goal here is
to have a single Ant file to build all of my sub-projects.
I am having some trouble getting a third party Ant project (call it
"foo") to run as a subproject to my "top-level" build project. The Foo
build runs just fine when Ant is run directly on it (in it's sub-dir),
but fails to run a jython script when called from my "top-level" build
file. Here's the failure output...
Buildfile: build.xml
foo:
bar:
[script] Traceback (innermost last):
[script] File "<string>", line 9, in ?
[script] ImportError: no module named buildUtil
BUILD FAILED
It fails because the script in the "bar" target cannot find cannot find
the buildUtil.py file. But the buildUtil.py file is located in the same
directory as the Foo build.xml file (see Directory Layout below)
I had thought that "dir" attribute of the "ant" task would change the
current directory context for scripts as well as the build.txt file.
It seems to me as if the "dir" attribute of the "ant" task in my
top-level build file does not change the working dir for the jyhon
script. Does this make sense?
Any suggestions? Thank you in advance.
