On error Redo some TasK

[Carlos Ortiz-2]

Hi,Here is my question, how do i redo or execute some task's when another
fail

for example , if targetA fail go to onErrorTargetATarget...

 <target name="targetA" >
        ....
    </target>

 <target name="onErrorTargetATarget" >
        ....
<delete ..... />
    </target>

been the main mainTarget


 <target name="mainTarget" depends="targetA, targetB, targetC" >
        ....
    </target>

thks in advance

There is no built-in mechanism for that.
If a task fails - the build fails.

You could try something with conditional targets and AntContrib:

<target name="targetA">
    <antcontrib:trycatch>
        ...
        <ac:catch>
            <property name="failed" value=""   description="A Failure somewhere"/>
            <property name="failed.A" value="" description="A Failure in 'A'. Just set the prop, value doesnt matter"/>
</target>
<target name="targetB">
    ...same...
</target>
<target name="onErrorTargetATarget" if="failed">
    <echo>Some targets failed.</echo>
    <echo>- TargetA: ${failed.A}</echo>
</target>
<target name="mainTarget" depends="targetA, targetB, targetC, onErrorTargetATarget" >
    ...

Ant usually fails on a failed task. There are certain tasks where this
rule could be overturned "those with a "failson" parameter, but most
of the time, if something fails, you really want to stop the build
process.

However, there is a special task in the AntContrib directory that I've
used before called <trycatch>. This task will execute a particular set
of tasks, then if there is an error, you can catch it and do something
else:
