Calling mvn from ant does not propagate errors

[Xavier Galleri <xa...@calyon.com>]

Hi,

I need to call mvn from ant and I tried to do that as follows:

    <exec executable="mvn.bat" failonerror="true">
      <arg line="install"/>
    </exec>

The problem is that the "failonerror" is not working when mvn fails. I'm
working under Windows XP.

After some investigations, I came to the conclusion that the errorlevel is
not correctly propagated back to ant when it execs the mvn.bat script.

To cope with that issue, I currently use a workaround, but it implies to
modify the "mvn.bat" script in order to:
  - trap errors slightly differently,
  - remove the /B from the final exit command.

Then, I renamed the modified "mvn.bat" file to "mvn-batch.bat" and create a
new "mvn.bat" file to do the following:

    @echo off
    cmd /c "mvn-batch.bat %*"

Eventually, I use the "mvn-batch.bat" file in my "exec" task:

    <exec executable="mvn-batch.bat" failonerror="true"/>

This way, the failonerror is working ok and ant failed as expected when mvn
fails!

To say the less, I'm a bit disappointed by the complexity of this solution!
Thus I would be pleased to get any feedback on this, especially if someone
could provide a better solution.

Any comments are welcome...

Rgds,
-Xavier

Using cruisecontrol is one reason.   Cruisecontrol calls ant which forks 
maven.  In that case, you definitely want to know if Maven failed so you 
can get cruisecontrol to report the failure properly.

Don't bother mentioning continuum.  It's not usable (yet, give them time) 
for a lot of people.  

Enjoy!

Hello,

Good to hear that you've made it work.  But then, I'm just curious as to why
you have to invoke Maven using Ant in the first place. :)

Cheers!
