As I was changing jet releases by switching IDE installations over the
same workspace I noticed that maybe this is not the case, while sure an
eclipse clean and rebuild workspace should scrap the jet2java classes
and regenerate them from the jet templates.

Edoardo:

JET does not just empty the jet2java directory on a clean. It will only
remove a file if JETs saved state indicates that the file was generated from
a JET template.

In thinking about it, clean could be more agressive. It could remove all
files marked as 'derived' in the jet2java folder.

But, if you are sure that you have included hand written code in jet2java,
you can just delete all of its contents by hand and rebuild. Leave the
jet2java folder itself, the JDT starts issuing errors if you delete it.

Paul,
I think a clean should really delete everything that's derived.

I noticed the prob because I was trying different builds (because of the
\ escaping) and I was expecting my generated code to change when it
didn't. It took a manual deletion of the jet2java files to get new java
files generated and subsequently see the difference in my generated code.

cheers

I'll take a look.
