I have quickly tried this plugin with actual Eclipse Kepler and it does not work well. Installing this plugin causes Eclipse to think that there are no compatible toolchains for current platform and even after unchecking the compatibility checkbox Buildroot toolchain is not there.
Yes I have to provide a new version compatible with the new version of CDT available in Kepler. It would be released soon, I expect at the end of next week.
Thanks for fast response, I'm looking forward new version...
The new version 3.0.0 is compatible with kepler. The update-site is available on http://buildroot.org/downloads/eclipse/kepler/.
