I found there is a undefined SCM status in my project, does anyone tell me what it does mean and why happened? Then what can I avoid such miss and solve it? Thanks a lot.
'?' is an item that is not under source control and '!' is an item that is under source control but the file is missing (deleted/moved/etc). Judging from the fact that you have two files with the same name where one has '?' and the other is '!', it looks like you probably moved the files around. You can resolve it by either delete the missing one and add the one not under version control or just move the files back.

In fact, I got error when compile with original png files, I thought I have to put those files onto top of project folder, so that I move them from original folder to new folder, at last, the "!" is displayed.
