allow importing into eclipse

[a1dutch]

This PR fixes the issue with not being able to import the project into eclipse using buildship (gradle integration). This is detailed in #1359.

Eclipse is able to have multiple projects unlike intellij which can only have one(i assume intellij sets the working directory to the root of this folder), eclipse sets it working directory to its workspace which is a different directory to its project directory. When it tries to find the last annotated tag via git its looking in the workspace directory which is not a git repo.

The fix simply adds the -C <project root directory> from the project so it can find the correct git repository.

I have imported the project into intellij and eclipse, all existing tests pass when run from a terminal.

I can confirm this fixed importing the project into eclipse (using the Spring Tools Suite 4 build of eclipse)

[a1dutch]

@dilipkrish any plans to get this merged?

[dilipkrish]

@a1dutch sorry for the really late reply. Im just coming out of a hiatus. I had a question about this change.

While this apparently doesn't have any problems, Im curious why the build system needs to know about how the IDE works?

[a1dutch]

@dilipkrish the issue is to do with how the ide’s set different working directories.

IntelliJ can only open a single project at a time and obviously sets the working directory to that project.

Eclipse on the other hand can import multiple projects into its workspace. The workspace is the working directory but not the directory of the project.

Gradle is aware of the absolute directory of the project it just needed to tell git what directory to use as the working directory is different
