I incorrectly posted this to GEF newsgroup - because all problems I
encountered
occured while I tried to get the code from a GEF example to run.
While I am very recent Eclipse "fan", I am by no means a novice. However,
after many hours of trying to comply with the instructions found on
www.eclipse.org/wep, I had to give up and ask for advice here. While doing
that, I would also like to contribute with some of my experience, that may
result with easy improvements :-)
I decided not to use the proposed location for the Workspace, when run
Eclipse for the first time - instead I opted to place it somewhere outside
Eclipse's tree. That resulted with a large number of difficulties,
indicating perhaps that such configuration may not have been given it's fair
share of testing. Trying to save my time figuring all these problems (which
I may enumerate in a different context), I removed the Eclipse and started
afresh.
Installing it the second time (really just expanding the archive at the
location of my preference), I also kept the default location for the
workspace, and the very first thing I tried was to add some additional
plugins, using the Eclipse's own UI (Help -> Software Updates -> Find and
Install menu item). This resulted with a number of additional features,
which I all accepted (These included the GEF and VE - which I was after. The
"Update Wizard" initiated the download, and that resulted with the first
problem:
1. Each of the selected features, is preceeded with the dialog warning that
the requested "package" is not signed, giving me the chance to reject it.
This is very inconvenient, since there is not a global override of such
control - one has to sit next to the keyboard and continue accepting the
stuff that was specifically selected in the first step of the Wizard.
Besides, why are these features not signed, then ?
Next, reading randomly throught various Eclipse newsgroups I realized that
many users complain that Eclipse will not recognize the newly added
features. There is a reference somewhere to run the Eclipse with an
additional argument (-clean if I remember it right), something no too
convenient using a desktop based link to the eclipse.exe. I also found the
alternative (if it realy is), accessible via Product Configuration Dialog,
which offers the service "Search for updates for all installed features".
This leads to the second inconvenience:
2. Using the "Search for updates for all installed features" results in a
(potentially) circular situation, as I got each time the offer to install
something different than what I already had for EMF SDK and the Examples for
EMF. The last versions offered to me were 2.0.1.R200409171617 - certainly
different from what I started when updating the initial configuration.
3. My real aim was to try one of the GEF examples, after reading all that
was available from www.eclipse.org/wep, (except the book referenced there).
Realizing that I do have all that's needed already installed (at least I
think so):
10/30/2004 07:50 PM <DIR> org.eclipse.gef.doc.isv_3.0.1
10/30/2004 07:49 PM <DIR> org.eclipse.gef.examples.flow_3.0.1
10/30/2004 07:49 PM <DIR> org.eclipse.gef.examples.logic_3.0.0
10/30/2004 07:49 PM <DIR> org.eclipse.gef.examples.source_3.0.1
10/30/2004 07:50 PM <DIR> org.eclipse.gef.source_3.0.1
10/30/2004 07:49 PM <DIR> org.eclipse.gef_3.0.1
I tried the instructions from the WEP FAQ page, which specifically says:
a.. How do I Run the Logic Example?
Download the example that matches your version of GEF. Exit Eclipse and
unzip into the eclipse directory. Restart Eclipse and verify it was
installed by going to Help->About Eclipse Platform->Plug-in Details and
checking for Logic GEF Example in the list. Next, create a simple Project.
Then run the Logic Wizard. The wizard can be found at File->New->Other
(Control+N), under the Examples heading. Select the simple project as the
container in which the wizard will place the example document. The document
should open automatically when you press Finish.
This is a very confusing paragraph since each of the instructions can be
interpreted more then one way. Rather than discussing semantics here, I will
just say that I am still not able to do anything with these instruction -
anything more than getting a simple project, whose contents would be a
..project file and flowExample2.flow file in the case I selected the Flow
Diagram example as suggested in the FAQ.
Can someone explain what's going on here? Should I have selected a project
of a different type as a container? I tried that to no avail.
Thanks in advance
