Simliar to https://github.com/diffplug/spotless/pull/1030 we could update to the latest CDT which is [11.4.0](https://projects.eclipse.org/projects/tools.cdt) if possible. I did not follow the changes in this repo w.r.t. the release process since the last update to CDT so I am not familiar on what is required exactly.
