clean way to stop building?

[Raf Colson <ra...@alcatel.be>]

Hello,

I was wandering if there exists a clean way to stop the buildproces, for
example when some resource (like a property file) is not available I
don't want the buildproces to continue. I'd like to see it stop with
some message indicating what was wrong.

greetings
Raf

In Ant 1.2 there's going to be a fail task for this. Until then the
only thing I can think of right now would be something like

<target name="check">
  <available property="ok" ...
</target>

<target name="fail" depends="check" unless="ok">
  <echo message="Resource not found" />
</target>

<target name="work" depends="check" if="ok">
...
</target>

<target name="check.and.run" depends="fail,work" />

which won't stop the build process but do nothing if things are not
set up correctly.

Stefan

Someone just submitted a patch a few hours to do just that may make it into
build soon (hopefully) - otherwise if you got a recent version there is a
task fail that can be used to do the same. You can make it exist in a
target that has unless="my-property" so that it will not get executed when
property is set. Then just add it into dependencie of all targets.

Cheers,

Pete
