How can I programmatically set up a IJavaProject whose classpath entries
include the full classpath available to some plugins ?
Elaboration:
I am writing a set of plugins that contribute a kind of project where
the user edits some type of emf model and then generates some java code
off it.
The generated java depends on some API that is included in my plugin code.
So the java project (created programmtaiclly by my wizard and by plugin
tests) must be set up so that it includes the api classes.
how do I do that
the classpath setup must be able to work both in development (eg when
these java projects are created in a runtime workbench) and in a
workbench where my plugins are properly deployed.

Thanks Sam, but I need to move on the next choice.
user project is a java (non-plugin) besides having nature 'mynature'.
The java build path needs to compile against some APIs that are included
in my plugin.
The problem is hitting me esp. for testing as when running in a runtime
workbench the following code fails,
while it works only when the code I need to reference lives in jar (like
when my plugin e.g. "org.junit' is deployed, say in jar 'junit.jar'):
IJavaProject javaProject ...
IPath path = findFileInPlugin("org.junit", "junit.jar");
if(path!=null) {
IClasspathEntry newEntry = JavaCore.newLibraryEntry(path, null, null);
addToClasspath(javaproject,newEntry);
}
//------
public static IPath findFileInPlugin(String pluginId, String
pluginRelativeFilePath)
throws MalformedURLException, IOException {
Bundle bundle = Platform.getBundle(pluginId);
if(bundle==null) {
return null;
}
URL pluginBundleURL = bundle.getEntry("/");
URL bundleURLForfile = new URL(pluginBundleURL,
pluginRelativeFilePath);
URL localURL = Platform.asLocalURL(bundleURLForfile);
return new Path(localURL.getPath());
}
public final static void addToClasspath(IJavaProject javaProject,
IClasspathEntry newEntry) throws JavaModelException {
IClasspathEntry[] oldEntries = javaProject.getRawClasspath();
IClasspathEntry[] newEntries = new
IClasspathEntry[oldEntries.length + 1];
System.arraycopy(oldEntries, 0, newEntries, 0, oldEntries.length);
newEntries[oldEntries.length] = newEntry;
javaProject.setRawClasspath(newEntries, null);
}
