Programmatically importing an existing project into Eclipse

Question

I am trying to importing the project to eclipse through programmatically. I dont want to use UI mode.

Below is the code I used for importing the project:

<         


        

Answer 1

Use org.eclipse.ui.wizards.datatransfer.ImportOperation

Try something like this:

IOverwriteQuery overwriteQuery = new IOverwriteQuery() {
        public String queryOverwrite(String file) { return ALL; }
};

String baseDir = // location of files to import
ImportOperation importOperation = new ImportOperation(project.getFullPath(),
        new File(baseDir), FileSystemStructureProvider.INSTANCE, overwriteQuery);
importOperation.setCreateContainerStructure(false);
importOperation.run(new NullProgressMonitor());

You're probably missing a line with

description.setLocation(new Path("/absolute/path/to/project/folder"));

Answer 3

I was able to use the following code to set focus to a newly imported project:

IProjectDescription description = ResourcesPlugin
  .getWorkspace()
  .loadProjectDescription(new Path("PROJECT_PATH/.project"));

description.setLocation(new Path("/absolute/path/to/project/folder"));

IProject project = ResourcesPlugin
  .getWorkspace()
  .getRoot()
  .getProject(description.getName());

project.create(description, null);
project.open(null);

Your code seems to be fine. What do you exactly mean by you couldn't get the source folder? Have you tried to refresh the project?

project.refreshLocal(IResource.DEPTH_INFINITE, new NullProgressMonitor());
