Wouldnt it contribute in over all build status.

My view is that ant is not designed to build several projects, with some 
projects failing and other being successful.
gump is really the tool that would be OK for this purpose.

Concerning your ants task, there was a proposal for something a bit 
similar called <antreturn/> which is a flavour of <ant/> which can 
return properties.

What you can do in ant 1.6 would be to use macrodef to describe the 
build of a generic subproject, and foreach or for from ant-contrib plus 
try/catch to get the status of each subproject

for instance (untested pseudocode)
macrodef build_one_subproject
try
build the subproject
catch
   <property name="[EMAIL PROTECTED]" value="true"/>
endmacrodef
<build_one_subproject sub-project-name="subproj_1"/>
<build_one_subproject sub-project-name="subproj_2"/>
<build_one_subproject sub-project-name="subproj_3"/>
<echo >${subroj_1-failure}</echo>
<echo >${subroj_2-failure}</echo>
<echo >${subroj_3-failure}</echo>
this would be doing what you would like.
You can probably iterate among your subprojects using for or foreach from 
ant-contrib.
Cheers,
Antoine

Hi All,
   Recently,  as part of automating my project builds, I have used 
CruiseControl along with Ant.  Surprisingly, I didn't find any task 
to build/compile all the subprojects    of a project.  My purpose was 
to have  the compile time errors of all the subprojects as part of 
automated build report. The 'ant' task will stop building as soon as 
one subproject fails. I tried using java/exec tasks with 'failonerror 
'  attribute as false, but the problem with  this approach is that 
build status of subprojects is not available to the main build 
process and resulting Total build successful though subprojects are 
failing in-between.
     

OK
   

  So, I have written new task  called 'ants' and used for my 
automated builds. This task internally uses 'ant' only.  What I would 
like to know is: Can I post this task of mine to apache or Is there 
any existing task/workaround available for the above required behavior.
     

Ant 1.6 has '<subant> that wil bulk compile a project ... does this do 
what you want or are there changes you'd recommend?
   

Also ant 1.6 has a -keep-going which will continue exectuting targets 
that do not rely on the task that failed.

Thanks in advance
