Continue executing ant script if one task fails

Question

I have an Ant script which runs tests then deploys my application to a QA server. To deploy the application it first calls sun-appserv undeploy, for various rea

Answer 1

I was looking for something similar to this and found an alternative method that is useful if you want to run a lot of tasks that have no dependency on each other and you want to know if all 5 of them fail without having to fix the first one.

Enclose all the tasks in a parallel task with threadCount set to 1. It's definitely a mis-use of the parallel task but accomplishes my goal:

<parallel threadCount="1">
    <fail message="fail 1"/>
    <fail message="fail 2"/>
    <echo message="Success"/>
    <fail message="fail 3"/>
</parallel>

Running this in a target gives this for output:

test:
     [echo] Success

BUILD FAILED
C:\test\build.xml:5:
fail 1
fail 2
fail 3

Total time: 0 seconds

Answer 2

See the -keep-going option documented here

Answer 3

AntContrib try catch:

<trycatch>
<try>
   <!-- do deployment getting return code -->
</try>
<catch>
   <!-- echo the return code with a message -->
</catch>
</trycatch>

The exec task has a failonerror attribute which you can set to false to keep going.
