在 Workspace 创建 resources
IWorkspace workspace = ResourcesPlugin.getWorkspace(); IWorkspaceRoot root = workspace.getRoot(); IProject project = root.getProject("MyProject"); IFolder folder = project.getFolder("Folder1"); IFile file = folder.getFile("hello.txt"); //at this point, no resources have been created if (!project.exists()) project.create(null); if (!project.isOpen()) project.open(null); if (!folder.exists()) folder.create(IResource.NONE, true, null); if (!file.exists()) { byte[] bytes = "File contents".getBytes(); InputStream source = new ByteArrayInputStream(bytes); file.create(source, IResource.NONE, null); }
