CodeClimate report in GitLab for c++ not showing

I am trying to activate the code climate report for merge requests pipelines in GitLab. The CodeClimate analyser is running but there are not shows any warnings when I add some bad code. There might be some configuration which I have missed.

I have added the following to my .gitlab-ci.yml file in the project rot folder:

include:
    - template: Code-Quality.gitlab-ci.yml

And I have added the .codeclimate.yml file looks like this:

plugins:
  cppcheck:
    enabled: true
    config:
      check: all
      language: c++
      stds:
        - c++14
        - c++17

The build job completes with the following lines at the end of the log:

f47a75dcba39: Pull complete
Digest: sha256:c8afb8c2037f7b9c5c9ae198aff00b1cf80db11d3591fbe89dfb3c69192663f1

What could be wrong here, since the merge request doesn't show any CodeClimate report?

In GitLab I have created one merge request with the configuration change (merging into master). And one merge request with some bad code, based on the first merge request with the configuration (merging into master).

The bad code:

int non_used_int;

int non_initialized_int;

int dummy = non_initialized_int;





// empty for loop
for (int i=0; i<100; i++) {

}

And a final note: I am using the shared GitLab runners provided by GitLab.

Guides I have followed:

Solution

[TLDR SCROLL DOWN TO SOLUTION]

you have to gain more control on your gitlab.yml file the best way to do so is by installing the gitlab-runner locally

after your gitlab-runner and docker are properly installed on your local machine

run it locally on your repository (you have to be inside your repository folder in the same path as .gitlab.yml file) start with a minimal .gitlab.yml file

the command to run locally is

sudo gitlab-runner exec docker <Task-Name>

for example lets take this minimal gitlab.yml file

image: walberla/cppcheck

cppcheck:
  script:
    - cppcheck --error-exitcode=1 .

the command will be

sudo gitlab-runner exec docker cppcheck

and the output will look like this :

now if everything works fine to follow the gitlab pipeline output for example i made a simple gitlab repo only containing your example file and gitlab.yml

https://gitlab.com/Naor-Tedgi/cpp-ci-runner/-/jobs/235981732

now we gain control on all the process you could see exactly what is going inside the ci and run the same process locally for example in the pipeline the image they using is docker:stable-did after runing the same steps you will understand what you are missing

keep in mind that because you are using docker in docker you will need to add --docker-privileged

 sudo gitlab-runner exec docker <Task-Name> --docker-privileged

[UPDATE! 20/06/19]

after our chat talk, and further investigation I created a simple example using code quality and the same gitlab.yml as mention above an got the same problem
