Unable to attain goal [build:end] -- null

[Gilles Dodinet <rh...@free.fr>]

hi-

im writing a plugin using mostly java and get a NPE at build:end when, 
and only when, a specific custom tag is called. ive searched google for 
this problem but didnot anything helpful (besides xref).

below the jelly scripts and the debug output. i dont think im doing 
fancy stuff in the tag however i attach it below - maybe is it relevant. 
also please note that the problem only appears when calling the goal 
pde:test defined in maven.xml (below).

thanks for your help !

i should certainly add that the tag executes normally (values correctly 
replaced in the specified files and zip files correctly constructed).

thanks.
