Problems with lpg.runtime and Eclipse 3.4? [message #21718]

Hello All

Thank you all for making this great framework. I am a new user of IMP,
trying to get it running on Eclipse 3.4.0, by following developer's
manual steps. However, I have a few problems, most of which associated
to lpg when running as a plug in:

1) First, when i get lpg.runtime.java project the lpgexe folder is empty
.. Then, I got the executable from lpgdistribution folder and place it
inside lpg.runtime.java project. Is this needed at all?

2) There are 3 run configurations available, and I used
"eclipse-3.2.2-1-L2", is that current? How can I have it on this
workspace without the need to deploy the plug-in every time? Since it
does not come up when I run the eclipse from the workspace normally.

3) Although LPG is available as an external tool in the development
eclipse workspace, it is not, in the workspace I installed the IMP
plugins. Moreover, in the IMP deployed one the lpg.runtime is shown in
the installed plug-ins but could not be found when it is referenced in a
sample project's Maifest file.

4) do I need to get ans deploy the project lpg.runtime.feature?

5) I used to get this error frequently. Although it might have been
cause by my miss-configuration I mention them, may be they help figuring
out the problem:

Also I forgot two add this one:

1)In the project org.eclipse.imp.releng the class WorkbenchReleaseTool
I commented out this line:
als.launch(buildScript, ILaunchManager.RUN_MODE, "build.update.zip");
since a method with this signature does not exists in my version of
AntLaunchShortcut. there are only these two:
+public void launch(ISelection selection, String mode)
+public void launch(AntElementNode node, String mode)

2) I think the problem number 5) was just because duplicate jars and
classloader confusion, so that one is actually solved.

Thank you,
Hamoun

The generator executable in lpgdistribution is very old, and (I believe)
incompatible with the latest runtime.

You should use the executable in lpg.generator.*/lpgexe, where "*" is
either macosx_x86, linux_x86, or win32_x86.

These launch configurations are intended for use by IMP developers,
as opposed to IDE developers using IMP. We've experienced numerous
problems with the set of enabled plugins in these launch configs
varying from person to person, despite the fact that the plugin set
is part of what gets checked into source control. For that reason,
I wouldn't expect them to work "out of the box".

You can do one of two things: (1) modify one of these launch configs
to include the IMP runtime and your IDE plugin(s), along with any
prerequisites, or (2) create your own runtime workbench launch config.
With either of these two approaches, you don't need to publish your
plugin to an update site (or export as a .zip file) just in order to
test it out.

Launch configurations are stored in the workspace (either in the
workspace meta-data folder, or in some project). Are you saying
that when you run your plugin in a runtime workbench (or "2nd-level
Eclipse" as we sometimes call it), you don't have the LPG external
tool launch? That's to be expected. If not, please clarify.

To be clear: are you saying that when you have IMP installed into your
Eclipse (say, using the Update Manager), workspace plugins that depend
on lpg.runtime don't resolve the dependency?

> 4) do I need to get ans deploy the project lpg.runtime.feature?

There are two answers to this question: the short-term answer and
the long-term answer. The long-term answer is only yes if your IDE
uses an LPG-based scanner/parser. The short-term answer is that at
the moment, there are one or two minor dependencies on lpg.runtime
in the IMP runtime, which would force you to deploy lpg.runtime
along with IMP. We plan to factor out these dependencies into
one or more separate plugins that can be omitted if your plugin
doesn't use LPG.

Thanks for reporting this! Annoying though this is, you can safely
ignore it for now; the presentation specification language (which
resides in o.e.i.presentation) is only half-baked, and nothing else
depends on it.
