Hi,
at the moment, our plugin uses getReferencedProjects() of IProject to
find out the referenced projects. However, this does not work if
projects in a second runtime Eclipse instance contain references to the
workspace of the "outer" Eclipse instance.
How do I get all referenced projects including references to external
folders?

This method returns an empty array in my case.

Actually, my goal is to find and load a referenced Ecore. The current
code works, except for external folders, and we want to fix this. See:

It might help or it might not. But I am not sure yet, that I fully
understand how this works. Could you please elaborate?

Well, actually the problematic code location looks as follows:
private EPackage[] getMetamodelsForProjectInternal(IJavaProject
project, Set<String> visited) {
if (visited.contains(project.getProject().getName()))
return new EPackage[0];
visited.add(project.getProject().getName());
ProjectAnalyzer projectAnalyzer =
getProjectAnalyzer(project.getProject());
if (projectAnalyzer == null) {
return new EPackage[0];
}
// wait if analyzation is currently executed
while (projectAnalyzer.getState() == Job.RUNNING ||
projectAnalyzer.getState() == Job.WAITING) {
try {
Thread.sleep(500l);
if (EmfToolsPlugin.trace)
System.out.println("Waiting 500ms for ProjectAnalyzer of project "
+ project.getProject().getName() + " to finish.");
} catch (InterruptedException e) {
EmfToolsLog.logError(e);
}
}
Map<String, EPackage> packages = new HashMap<String,
EPackage>(projectAnalyzer.getNamedEPackageMap());
try {
for (IProject p : project.getProject().getReferencedProjects()) {
IJavaProject jp = JavaCore.create(p);
EPackage[] ps = getMetamodelsForProjectInternal(jp, visited);
for (EPackage package1 : ps) {
if (!packages.containsKey(package1.getNsURI())) {
packages.put(package1.getNsURI(), package1);
}
}
}
} catch (CoreException e) {
EmfToolsLog.logError(e);
}
return packages.values().toArray(new
EPackage[packages.values().size()]);
}
The ProjectAnalyzer mentioned in the code, tries to obtain an IResource
to the found Ecore file. The problem is that all this does not work, if
the Ecore model is located in an external folder.

Ok. Is there currently a possible design that would be able to find
models in the workspace, inside deployed plugins, *and* external
folders?

Patrick,
In the workspace you could do what you have now. In deployed plugins,
it's possible to force the plugin URL to be converted to a file URL, and
of course that turns it into the final case of pawing through the file
system directly. It's probably good to take a step back and look
consider very carefully how what's being done here is similar to the way
PDE manages and provides access to the target platform... You might
want to treat the problem you're trying to fix as a short term
limitation. Perhaps when I'm in Germany the week of Oct 13th we can
discuss the design choices...
