I have such notificaton in IDEA 12

Root 'D:/myproject' is likely to be of unsupported Subversion format

And such error on trying to update from IDEA 12

Error updating changes: svn: E155021: The client is too old to work with the working copy at "..." (format 31).

I've checked out sources with commandline client v 1.8.5

It creates working copy with format/entries 12. (it is 1.7 I suppose) IDEA 12 supports 1.7 subversion

What could cause such problem?

There's your answer:

I've checked out sources with commandline client v 1.8.5

Working copies that were created using svn 1.8+ cannot be used at all with any svn client 1.7 or less. You need to either use another command line client or do the checkout using IDEA.

  • What command did you use for the checkout? If you used a 1.8 client and issued something like `svn checkout xxx`, it will be a 1.8 working copy. – Michael Schlottke-Lakemper Dec 27 '13 at 18:55
  • Well, then it will be a 1.8 working copy, and not readable by IDEA. The `format` file was only used up to version `1.7` I think, after that the actual version number of the wc layout can be found as described in this post: http://stackoverflow.com/a/19272304/1329844 – Michael Schlottke-Lakemper Dec 30 '13 at 08:28
  • Agreed. SVN 1.8 is supported only since IDEA 13. See [this question](http://stackoverflow.com/q/20797443/579828) – Vic Dec 30 '13 at 09:26
