nios2-build-project command line

Hi,

I've got some problems about the "nios2-build-project" command line :

when i type this command, i've got the following warnings which appear on my screen :

!ENTRY org.eclipse.osgi 4 0 2009-10-08 09:51:00.906

and nothing has occured

Is anybody can help me ?
