You're getting stuck by several things at once. As it turns out GVC is one of the trickier frameworks to just import into Eclipse because they don't use the Eclipse incremental compiler. Their projects are wired with the ant builder and they depend on a design- by-contract preprocessor step. So what you're seeing is ant freaking out trying to build the project and I'm assuming it can't find the ant plugins/tasks necessary to actually pull it off. Their frameworks also define several classpath variables that you need to set to allow it to build. They may document the exact steps to import their frameworks into Eclipse -- if anyone has docs, it's Chuck, that's for damn sure.

:-P Though, looking at them, they need some version number updating.



Lastly, it would APPEAR that out-of-the-box the GVC frameworks (I just attempted this import as well) trip some exception inside of Eclipse itself. What you're seeing with the disappearing project contents is that when you turn down the arrow, something inside of Eclipse is throwing an exception in the processing of the java model for that project. If you were to open the Errors View (not Problems view -- Errors view, which is mostly a developer view that you don't really need) you would see there are some crazy really low level exceptions. I've honestly never seen these errors before, so maybe Chuck can shed some light on his import process.

_if_ Eclipse is properly configured, there should be no errors. I have seen some classpath error occasionally that I am unable to explain. What exceptions are you seeing?



I would recommend starting smaller than this ... You're jumping into Eclipse development by importing an enormous set of interdependent projects (that use a custom build process). Go through the initial tutorials first. Chuck has written some tutorials for importing projects from Xcode, too, that you might want to go through.

I have? There is one here, but it is not mine. Though I may well have written others and forgotten about them already.




If you want to charge headstrong into working with a big set of frameworks, Project Wonder is actually probably an easier import. It's a very "traditional" set of Eclipse/WOLips projects that should import and build cleanly out-of-the-box (no ant dependencies, etc) either from CVS/SVN or from the filesystem.

Yes, Wonder is what I aspire to. And will reach once we can ditch this Ant builder.

I'm trying to dive into Eclipse/WOLips and just to understand how a
full project is supposed to look w/ packages,etc, I downloaded GVC's
wonderful FrameWorks source. I can use the Import option in Eclipse to
import from these pre-existing projects. However, it starts to
immediately build them, having trouble the ant function and certain
lacking other frameworks. That's perhaps all fine and good. What gets
me is that every project (with an x on it now) has a pull down bar.
Clicking on the project in the package explorer "loses" the expansion
arrow and its empty.


Would someone who groks eclipse care to tell me whats going on with
this poor UI, and why I can't access any files that were just imported
and processed. It saw them, and now its telling me its all off limits,
so how can I fix anything?
