IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot(); IProject project = root.getProject("MyProject"); if (project.isOpen()) { System.out.println("Project is open."); } else { System.out.println("Project is closed."); }In this code snippet, we use the ResourcesPlugin to get the workspace root and then get the project "MyProject". We check if the project is open using the isOpen method and then print the appropriate message. The package library for org.eclipse.core.resources is Eclipse Platform Core Resources.
