Creating a Eclipse Java Project from another project, programatically

I would like to create a Java project from another Java project, using some script or Java methods from an Eclipse library, whether it exists. An alternative to this can be duplicating a previously manually-created project. Is there any approach to this?

Thanks.

Adding to Alexander Pavlov's answer, I found that a little extra work is required to copy the project properties (such as referenced projects) in addition to just copying the project files. 

public static IProject copyProject(String projectName) throws CoreException {
    IProgressMonitor m = new NullProgressMonitor();
    IWorkspaceRoot workspaceRoot = ResourcesPlugin.getWorkspace().getRoot();
    IProject project = workspaceRoot.getProject(projectName);
    IProjectDescription projectDescription = project.getDescription();
    String cloneName = projectName + "_copy";
    // create clone project in workspace
    IProjectDescription cloneDescription = workspaceRoot.getWorkspace().newProjectDescription(cloneName);
    // copy project files
    project.copy(cloneDescription, true, m);
    IProject clone = workspaceRoot.getProject(cloneName);
    // copy the project properties
    cloneDescription.setNatureIds(projectDescription.getNatureIds());
    cloneDescription.setReferencedProjects(projectDescription.getReferencedProjects());
    cloneDescription.setDynamicReferences(projectDescription.getDynamicReferences());
    cloneDescription.setBuildSpec(projectDescription.getBuildSpec());
    cloneDescription.setReferencedProjects(projectDescription.getReferencedProjects());
    clone.setDescription(cloneDescription, null);
    return clone;
}

I believe you can make use of IProject#copy (inherited from IResource.copy)
