This at least made clear to me that the vendor branching isn't the
problem with expresso because of the way expresso is wrapped around my
own code. The problem is that I need to restructure the expresso sources
to be able to use it in Eclipse. This doesn't play nicely with vendor
branching.
I suppose there isn't a way to do tranparent restructuring while
merging, or is there? I could off course do seperate merges for every
directory I want to place somewhere in my source-tree. That's one
option. The other option is just using the expresso source just as it
is. It contains files and directories I really don't need, but
everything I need (the webapplication) is placed inside a sub-folder
named 'expresso-web'. In Eclipse (with the sysdeo tomcat-plugin) it is
possible to tell Eclipse that a project's web-application isn't in the
project's root. So I could specify 'expresso-web' here. This produces
the least administrative overhead, so I think i'll go with it. The only
disavantage is having unnecessary expresso files and directories hanging
around, but even these things like ANT-buildfiles might prove usefull
one day.
Hmmm.. Somehow I feel like it wasn't such a big problem anyway, I just
needed to have a better overview of the possibilities.... TNX for making
things clear...
