Re: [NAnt-users] Perform task on error? or try/finally

[Weintraub, D. <dav...@bo...>]

You can use the Nant "nant.onfailure" property to specify the name of
the task to run on a task failure:
 
     <property name="nant.onfailure" value="revert"/>
 
The above will run the Nant task "revert" when a Nant task returns an
error. You could then have the "revert" task do your cleanup.

	Hi all,

	 

	I have a task which runs an external program. That program
generates some output files to a specific folder. Once that is done I
copy those files to our output folder and delete the program's output
folder.

	 

	<target name="doFoo">

	    <exec program="foo.exe">

	        <arg line="/o:./FooOutput"/>

	    </exec>

	    <copy todir="./ProjectOutput">

	        <fileset ....../>

	    </copy>

	    <delete dir="./FooOutput"/>          <=== Would like this to
run even if the <exec> fails

	</target>

	 

	 

	If the external program fails, I would like to delete its output
folder to clean it up since those output files are not valid. 

	 

	Is there some way to specify that a sub-task should run even if
a previous task failed? Can I create another target where I execute the
program, then in the main target delete the folder and still have Nant
record a failed build? Is there a try/finally type of construct?

	 

	Thanks,

	- Josh
