ant call on exit

[Jake Ewerdt <ja...@emeta.com>]

My build.xml file creates a lock file at the beginning and deletes it at the 
end.  However, if there is a problem with compiling or the unittests, that 
lockfile doesn't get deleted.  Is there some way to specify that a target 
gets called on exit (preferrably even SIGINT)?

I read in the documentation that you can write a listener that gets called 
when the build exits, but will that listener get called if the build does not 
exit successfully?

Thanks,

Yes.  To detect an error, the buildFinished event will have an 
exception attached to it.  Have a look at the built-in loggers and 
listeners for examples (the MailLogger, for example, detects whether an 
error occurred or not).

Jake,

We had similar problems (long ago). We wrote the <protect> task in
AntXtras to solve this problem. FYI:

    [create lock]
    <protect>
       [do stuff that can signal error]
       <always>
          [release lock]
       </always>
    </protect>
