Getting "CHECKOUT can only be performed on a version resource" when trying to commit using Eclipse subversive plugin

Cleaning up worked for me:

right click on the project -> team -> cleanup / refresh

This is most likely your console svn version is different to your Eclipse "SVNKIT (Pure Java)" version, you can change Preferences=>Team=>SVN=>SVN interface=>Client using "JavaHL (JNI)"

My case is as below, using Java HL 1.7.10 is ok, but using SVNKIt v1.7.9 will have the problem

wuliang-Mac:src wwu$ svn --version
svn, version 1.7.10 (r1485443)
compiled Jul  9 2013, 12:55:03

As I commented in other post...

For those that project -> team -> cleanup doesn't work in eclipse try:

• Force the cleanup using SVN Tortoise
• From terminal with command svn cleanup /folder_to_cleanup
