org.apache.subversion.javahl.ClientException - client is too old

Question

I get the following error message when I try to compare files in Eclipse using Subclipse:

Unsupported working copy format svn: This client is too old to work with the working copy at 'C:\XXX' (format 31). You need to get a newer Subversion client. For more details, see http://subversion.apache.org/faq.html#working-copy-format-change.

I'm using, svn (command line): 1.8.0, Subclipse: 1.8.22, Subversion JavaHL: 1.7.10.

What could be wrong?

Answer 1

Upgrade Subclipse plugin to the latest 1.10.x version. Subclipse 1.8.x works with SVN 1.7 and requires to be upgraded to 1.10.x in order to work with SVN 1.8 working copies.

Answer 2

I faced similar issue after updating working copy from Tortoise SVN.

Issue fixed by upgrading Subclipse plugin to latest 1.10.x version. Update performed by searching in Help -> Eclipse Marketplace.
