Thanks Edward for your suggestion !!.
I have already followed the hard coded
string approach suggested by you before posting the problem in forum but no success in nailing down the problem.
All the arguments looks correct to me while debugging . here is the summary of echo statements
${appc.additional.options} =""
${bmwslc.param.options} ="-forceGeneration"
${_appc.input}="test_ear-generic.ear"
I am dumb struck because all the parameters seems to be correct
Please suggest any other thoughts , which you have in mind .
Thanks in advance !
Regards
