ant - subant failonerror subtleties -

I have an entry code that closes the release build in all the subdirectories:

  & Lt; Target name = "all-release" & gt; & Lt; Subant target = "sub-release" failure = "true" & gt; & Lt; Fileset dir = "." Includes = "* / build.xml" /> & Lt; / Subant> & Lt; / Target & gt;  

In the written form, if any person's build fails, all-release will fail rapidly (no later construction will be successful. If I failonerror = " False ", all the releases will be successful at all times. It has been discovered that all sub-builds are independent, so what do I need:

Run all sub-release constructions, and after that All releases fail after one or more sub-rings (Ideally a good error message about which fails).

Any ideas?
