**Description**

I get the following error when trying to open a Project that previously worked. We use a git repository, and I am the only one, out of a team of 6 that is getting this error.

I tried changing the version number on the repository to the latest version (6.2.2) as a previous post on the community stated that this might fix the problem, but the error still appeared.

Hi @etienne.venter,

Please delete .project and .classpath file then reopen KS again.  
You should put .project and .classpath file in .gitignore file.

Thanks.
