We are developing an eclipse plug-in.
We want to know the list of jars on the classPath of the selected project.
We have the IProject object of the selected project.
How do we get the full paths of jars on the classPath of the project?
Thanks in advance.

Prasanna,

Here's a snip of code that should help you get started:

IJavaProject javaProject = JavaCore.create(project);
urls.add(new File(project.getLocation() + "/" +
javaProject.getOutputLocation().removeFirstSegments(1) + "/").toURL());

// Compute the URLs for all the output folder of all
the project dependencies.
//
for (IClasspathEntry classpathEntry :
javaProject.getResolvedClasspath(true))
{
if (classpathEntry.getEntryKind() ==
IClasspathEntry.CPE_PROJECT)
{
IPath projectPath = classpathEntry.getPath();
IProject otherProject =
workspace.getRoot().getProject(projectPath.segment(0));
IJavaProject otherJavaProject =
JavaCore.create(otherProject);
urls.add(new File(otherProject.getLocation() +
"/" + otherJavaProject.getOutputLocation().removeFirstSegments(1) +
"/").toURL());
}
}

The idea is you need to get at the IJavaProject and analyze the class
path for that.

Hi Ed,
Thanks for your reply.
After going through the code snippet you had posted, I checked out the
javadoc for IClasspathEntry.
This is how I got full paths (on file system) of all the jars on the
classPath of the selected project :

List<String> classPathEntriesList = new ArrayList<String>();
IJavaProject javaProject = JavaCore.create(project);
IClasspathEntry[] classPathEntries = javaProject.getRawClasspath();
for(IClasspathEntry classPathEntry : classPathEntries) {
if( classPathEntry.getContentKind() ==
IPackageFragmentRoot.K_BINARY)
classPathEntriesList.add(classPathEntry.getPath().toString() );
}
for(ListIterator<String> it = classPathEntriesList.listIterator();
it.hasNext();) {
classPath += it.next();
if(it.hasNext())
classPath += ";";
}

This link helped me :

I'd like to know What do I stand to loose if I don't follow the road-map
shown by you.

Thanks.

Prasanna,

I'm not an expert on this by any means. I just snipped some code from
one of the classes I on in the past to help get you started. It's been
a while since I looked at code for this...
