Hello all

I am searching for some documentation w.r.t launching an Ant Task from an EGF Activity.

I have found code and explanation of how to do a Java Task, but my goal is to try to launch an Ant Script from EGF.

Any help would be appreciated.

Thank you

Hello Catalin,

You have an example of Ant task.
- Import the EGF Basic examples.
- Open the "ant_task.fcore" of the "org.eclipse.egf.example.task.ant" plugin, you will find the "ant_task" example.

Double-click on the Task, and you will directly access to the Ant script.

Next, you right-click on the task to run it, or you can invoke it in a production plan of a factory component.

Hi Benoit

Thank you for your response.
Unfortunately when i run this example on Juno and also Kepler, also on two different PCs
I get the following error
:

'Run EGF Activity ...' has encountered a problem.
Unexpected exception while instantiating class 'HelloWorld' in bundle 'org.eclipse.egf.example.task.ant'.
java.lang.NullPointerException


Any ideas will be helpful.

Thank you

Hi,

I tested this example on juno and I got the expected output:
main:
     [echo] Ant task says Hello !

BUILD SUCCESSFUL
Total time: 0 seconds

Could you post the full stacktrace of the NPE ?

Best regards,
Thomas

Hi Thomas

Thank you for your response.
Could tell me more precisely how to do that ? I am still in the process of learning acronyms and eclipse terminology.

Thank you
