What You Are Seeing?

I'm having problems to get the git version of a repo using Cake.Git.
I think that the problem has something to do with the relative path for the .so file.

What is Expected?

Get the latest tag of the repo.

What version of Cake are you using?

• 0.22.1

Are you running on a 32 or 64 bit system?

• 64

What environment are you running on? Windows? Linux? Mac?

I'm using a docker image to build my project (or trying to).
Image: johnnyasantoss/dotnet-mono-docker:dotnet2.0-mono5.2-sdk

How Did You Get This To Happen? (Steps to Reproduce)

I tried to run a task and after compiling I got this error message.

This is the dockerfile that I'm using https://github.com/johnnyasantoss/JsonFluentMap/blob/testes-unitarios/Dockerfile

I have the same issue, @patriksvensson .

Repro non-working Cake.Git on Linux: https://travis-ci.org/johnkors/cakegit/jobs/351972745#L2503

A workaround/fix from @devlead on gitter.im: Using a Ubuntu base image instead of say Debian based ( microsoft/sdk-2.1 is Debian based when on Linux containers).

Example of working Ubuntu image: FROM devlead/bitbucket-pipelines-dotnet.

Seems to be related to
libgit2/libgit2sharp#1533

I'm getting this issue as well. I've tried the posted workaround, and it had no effect :( here's the error I'm getting (note this is gitversion throwing the error):
