[news.eclipse.modeling.m2m] Re: [ATL] Ant task problem

[William Piers <william.piers@xxxxxxx>]

Hello,

A documentation about ATL ant tasks can be found here: 
http://wiki.eclipse.org/ATL/User_Guide#ATL_ant_tasks

Do not forget to modify the launch configuration as specified here: 
http://wiki.eclipse.org/ATL/User_Guide#Launching_an_Ant_file_with_ATL_tasks_in_an_Eclipse_workbench 
before launching.

Best regards,

William
