Eclipse Clearcase plugin: Error making file(s) writable

Question

I'm trying to use Rational SCM Adapter 7.5 on Eclipse 3.5 on a Linux machine.

The plugin installation was successful and the clearcase menus all appear correctly. But, I'm unable to checkout the file via Package Explorer -> Team -> Checkout. The checkout dialog does not appear.

When I try to edit the file in the editor pane, the Checkout dialog appears. But, when I try to checkout the file, I get the following error:

!ENTRY com.rational.clearcase.linux 4 0 2011-04-15 03:35:38.469
!MESSAGE CCFileModificationValidator::validateEdit: Error making file(s) writeable
User canceled checkout or checkout failed:

Answer 1

That seems to be a current bug, only fixed in Rational Application Developer for WebSphere Software 7.5.3, but not back-ported yet in the Rational SCM adapter 7.5.0.

(Even though the p2 update site http://www3.software.ibm.com/ibmdl/pub/software/rationalsdp/clearcase/60/update/windows/ shows a com.rational.clearcase_7.5.0.v201102110950.jar quite recent)
