Running ReportGenerator global tool on Gitlab runner is broken - v 4.4.4

I’m setting up a dotnetcore 3.1.1 codebase, and trying to incorporate the reportgenerator globaltool as part of the CI process.

But, even though the same shell script works on my local (mac os catalina), the command fails on CI. The command that I am running is:

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=./TestResults/Coverage/ && ./tools/reportgenerator '-reports:./api.test/TestResults/Coverage/coverage.cobertura.xml' '-targetdir:./api.test/TestResults/Coverage/Reports' -reportTypes:Html

(This is the content of the test.sh shell script)

I tried to reproduce this issue but it worked in my environment. I tried two setups:

• Ubuntu with shell executor
• Ubuntu with docker executor

I created the following setups:

Ubuntu with shell executor

1. Installed Ubuntu 19.10 with latest updates
2. Installed .NET Core SDK 3.1 (see https://docs.microsoft.com/de-de/dotnet/core/install/linux-package-manager-ubuntu-1910)
3. Installed Gitlab Agent as a service (see https://docs.gitlab.com/runner/install/linux-manually.html)
4. Registered Gitlab Agent as shell executor (see https://docs.gitlab.com/runner/register/index.html#gnulinux)

My .gitlab-ci.yml

stages:
  - build

build_job:
  stage: build
  script:
    - dotnet tool restore
    - dotnet reportgenerator -reports:OpenCover.xml -targetdir:out

Ubuntu with docker executor

1. Installed Ubuntu 19.10 with latest updates
2. Installed Docker (see https://docs.docker.com/engine/install/ubuntu/)
3. Installed Gitlab Agent as a service (see https://docs.gitlab.com/runner/install/linux-manually.html)
4. Registered Gitlab Agent as docker executor (see https://docs.gitlab.com/runner/register/index.html#gnulinux)

My .gitlab-ci.yml

image: mcr.microsoft.com/dotnet/core/sdk:3.1

stages:
  - build

build_job:
  stage: build
  script:
    - dotnet tool restore
    - dotnet reportgenerator -reports:OpenCover.xml -targetdir:out
