I have transferred all springframwork files to ~/.m2/repository/org/ folder
How did you do this? Hopefully by running "mvn install:install-file ..." for each JAR. If you didn't, then your local repository is not well defined (missing metadata) and thus Maven will ignore the files. Showing the directories under ~/.m2/repository/org/springframework doesn't help - I really need to see the full directory tree and files (just for ~/.m2/repository/org/springframework/spring would be sufficient because that is the specific one mentioned in the error message).
Also, I am going to cross-link your post to the Spring forum, perhaps someone there will know the URL for the Spring Maven repository. (It doesn't help that the URLs provided by the FAQ I mentioned earlier don't let you browse the repository; it makes finding anything a guessing game.)
