Nant "nant.onsuccess" property - nant

Question

I have a nant file which does the building of my project. Once the build succeeded, I will use the nant.onsuccess property to send mail. In this nant.onsuccess I will call next batch of targets to build. But I need to send the mail depending on the success or failure of these set of targets that are called from the nant.onsuccess target.
eg:
<?xml version="1.0" encoding="utf-8" ?>
<project name="Build.build" default="default">
<property name="mail.mailhost" value="x"/>
<property name="mail.from" value="y"/>
<property name="mail.to" value="z"/>
<target name="default" description="Just like that">
<echo message="Succeeded"/>
<echo message="Succeeded"/>
<property name="nant.onsuccess" value="suc"/>
</target>
<target name="suc" description="Just like that">
<echo message="I am called"/>
<echo message="in success part"/>
<property name="nant.onsuccess" value="here"/>
<call target="testing"/>
</target>
<target name="testing">
<echo message="I ammmmmmmmmm"/>
<property name="nant.onsuccess" value="here"/>
</target>
<target name="here">
<echo message="I should not be called"/>
</target>
<target name="nant.onfailure">
<if test="${string::get-length(mail.to) > 0}">
<mail mailhost="${mail.mailhost}" from="${mail.from}" tolist="${mail.to}"
subject="Test mail on ${environment::get-variable('COMPUTERNAME')}.">
Note: this is ignored.
</mail>
</if>
</target>
</project>
The target "here" should be called depending on whether the target "testing" is succeeded or not.
Please let me know how do i achieve it.
Thanks,
Priya

Answer 1

Once nant finished its build it will execute a target specified by nant.onsuccess or nant.onfailure. This happens only once, so if you change the nant.onsucces / nant.onfailure properties it will have no effect.
As other posters stated for implementing conditional logic target dependencies, <if>, <trycatch>,<choose> and the <nant> and <call> tasks together with the if / unless attributes are better suited.

Answer 2

First thing to understand is how target dependencies can control execution. You can probably do a lot of what you need just by using dependencies. Read through the NAnt fundamentals page on targets.
Next, if you have to do a lot of logic depending on whether a particular task fails, you might check out the <trycatch> task in the NAntContrib project, which adds many useful tasks to NAnt. The trycatch task allows for a lot more flexibility than the default nant.onfailure.

I am not sure , if this will help. please give a look at below link.
I have put together a sample build file.
