Suggest you look at the extensions available in the ant-contrib tasks.

The 'for' task can probably be adapted to meet your requirements.

Using some other ant-contrib features it may be possible to get the list of fails.

Sample log from above build.xml:

$ ant all-release
Buildfile: build.xml

all-release:
     [echo] /work/Scratch/dir1/build.xml

sub-release:
     [echo] dir1
     [echo] /work/Scratch/dir2/build.xml

sub-release:
     [echo] dir2
      [for] /work/Scratch/dir2/build.xml: The following error occurred while executing this line:
      [for] /work/Scratch/build.xml:17: The following error occurred while executing this line:
      [for] /work/Scratch/dir2/build.xml:6: dir2 failed
     [echo] /work/Scratch/dir3/build.xml

sub-release:
     [echo] dir3

BUILD FAILED
/work/Scratch/build.xml:11: Keepgoing execution: 1 of 3 iterations failed.
