  • 0

Every time I try to install updates on to eclipse ide it fails with constraint validation error. E.g. eclipse shows me list of plugins which needs to be updated, I select them all and on the pahase of constraint checking it fails saying that only one version of a plugin can be installed.

How to fix it?

UPD

Cannot complete the install because of a conflicting dependency.

    This constraint means that during the update the system has found incompatible versions of plug-ins: they are depending on the same plug-in.

    Check the Error log view of the Eclipse where you can find a more detailed message from that you can trace back the offending plug-in (it is not the simplest description possible to determine the conflicting plug-ins, but I don’t know of any other type of p2 update logger facility).

    EDIT: It seems to me from checking the error message, that the update found an update for the CDO Model Repository CLient, but did not for the Repository Server Hibernate Component. I would try to add the CDO 4.0-corresponding update site location from http://wiki.eclipse.org/CDO/Hibernate_Store/Download_and_Install#Update_site_locations (at least if this is what you use for Hibernate support in COD).

    Otherwise I would try (after backing up your Eclipse folder) to uninstall the Hibernate component, and then update, then finding the correct location of the CDO Hibernate component you are using.
