import re-imports top-level build.xml
When <import> is given the same path twice, it skips the second import.
However, if <import> is given a path to the original (top-level)
build-file, it does not consider it a duplicate import, and imports it
(again) ... unless ant is invoked as "ant -f /full/path/to/build.xml" -
then import does recognize that the file has already been imported.
I would expect that import should not (ever) import the top-level build
file again.
Is this a bug? I can submit a bug report and try to fix it.
Why import the top-level file? In a (parent, subproject1, subproject2,
subproject3) setup, my parent project imports the subprojects and the
subprojects import the parents - subprojects do not import each other.
When the parent is built, the top-level project imports subproject A,
and subproject A imports the parent. The import of the parent is not
suppressed because the top-level build was not invoked with a full-path
to the build file, and confusion ensues.
Example:
$ cat build.xml
<project name="test">
<echo message="test-top" />
<import file="./build.xml" />
<echo message="test-bottom" />
</project>
$ ant
Buildfile: build.xml
[echo] test-top
[echo] test-top
[echo] test-bottom
[echo] test-bottom
BUILD SUCCESSFUL
Total time: 0 seconds
$ ant -f $PWD/build.xml
Buildfile: /a/vallon/tmp/tmp.20080128/build.xml
[echo] test-top
[echo] test-bottom
BUILD SUCCESSFUL
Total time: 0 seconds
$ ant -version

That does sound like a bug!.
Please file a bugzilla report.
