SonarQube with Travis not showing issues on dot net core 2 project - .net-core

Question

I have a simple dotnet core 2.0 project with a simple issue which is failing SonarLint with an unused variable issue.
The code is stored in a public github repository (here). A travis job (here) runs and has the SonarQube plugin and should post to SonarCloud (here).
The problem I have is that this issue is not being picked up by the analysis and published as an issue. I obviously have something set up incorrectly but I dont know what.
My .travis.yml is below
language: csharp
dist: xenial
sudo: required
mono: none
dotnet: 2.0.0
solution: Dibware.Salon.sln
addons:
sonarcloud:
organization: "dibley1973-github" # the key of the org you chose at step #3
token:
secure: $SONAR_TOKEN
branches:
only:
- master
before_script:
- chmod +x build.sh
- chmod +x run-tests.sh
script:
- ./build.sh
- ./run-tests.sh
- sonar-scanner
My sonar-project.properties file is below
# Project identification
sonar.projectKey=Core:Dibware.Salon
sonar.projectVersion=1.0.0.0
sonar.projectName=Dibware.Salon
# Info required for SonarQube
sonar.sources=./Domain
sonar.language=cs
sonar.sourceEncoding=UTF-8
C# Settings
sonar.dotnet.visualstudio.solution=Dibware.Salon.sln
# MSBuild
sonar.dotnet.buildConfiguration=Release
sonar.dotnet.buildPlatform=Any CPU
# StyleCop
sonar.stylecop.mode=
# SCM
sonar.scm.enabled=false
In the travis log I do have:
INFO: 27 files to be analyzed
WARN: Shallow clone detected, no blame information will be provided. You can convert to non-shallow with 'git fetch --unshallow'.
INFO: 0/27 files analyzed
WARN: Missing blame information for the following files:

INFO: More about the report processing at https://sonarcloud.io/api/ce/task?id=AWo0YQeAUanQDuOXxh79

Is this what is affecting the analysis? If so how do I resolve it? If not what else is stopping the analysis of the files, please?
EDIT:
I can see the following in the log, but it still does not get picked up by SoanrQube..
Chair.cs(17,17): warning CS0219: The variable 'a' is assigned but its value is never used
Edit 2:
I managed to getthe analzed number to go up, see below...
INFO: Sensor Zero Coverage Sensor
INFO: Sensor Zero Coverage Sensor (done) | time=6ms
INFO: SCM provider for this project is: git
INFO: 27 files to be analyzed
INFO: 27/27 files analyzed

... using the following in my .travis.yml
install:
- git fetch --unshallow --tags

Answer 1

Ok, I am not out of the wood yet, but am getting some analysis using the following .travis.yml
language: csharp
dist: xenial
sudo: required
mono: none
dotnet: 2.1.300
solution: Dibware.Salon.sln
addons:
sonarcloud:
organization: "dibley1973-github" # the key of the org you chose at step #3
token:
secure: $SONAR_TOKEN
branches:
only:
- master
install:
- dotnet tool install --global dotnet-sonarscanner
- git fetch --unshallow --tags
before_script:
- export PATH="$PATH:$HOME/.dotnet/tools"
- chmod +x build.sh
- chmod +x run-tests.sh
script:
- dotnet sonarscanner begin /k:"Core:Dibware.Salon" /d:sonar.login="$SONAR_TOKEN" /d:sonar.exclusions="**/bin/**/*,**/obj/**/*" /d:sonar.cs.opencover.reportsPaths="lcov.opencover.xml" || true
- ./build.sh
- ./run-tests.sh
- dotnet sonarscanner end /d:sonar.login="$SONAR_TOKEN" || true

Answer 2

In the end the travis.yml file I used which worked is this:
language: csharp
dist: xenial
sudo: required
mono: none
dotnet: 2.1.300
solution: Dibware.Salon.sln
addons:
sonarcloud:
organization: "dibley1973-github" # the key of the org you chose at step #3
token:
secure: $SONAR_TOKEN
branches:
only:
- master
install:
- dotnet tool install --global dotnet-sonarscanner
- git fetch --unshallow --tags
before_script:
- export PATH="$PATH:$HOME/.dotnet/tools"
- chmod +x build.sh
- chmod +x run-tests.sh
script:
- dotnet sonarscanner begin /k:"Core:Dibware.Salon" /d:sonar.login="$SONAR_TOKEN" /d:sonar.cs.opencover.reportsPaths="**/coverage.opencover.xml" /d:sonar.exclusions="**/bin/**/*,**/obj/**/*,**/Dibware.Salon.Web/**/*" || true
- ./build.sh
- ./run-tests.sh
- dotnet sonarscanner end /d:sonar.login="$SONAR_TOKEN" || true
The build file is this.
#!/usr/bin/env bash
dotnet restore
dotnet clean -c Release
dotnet build Dibware.Salon.sln -c Release
The test is this.
# Run the tests and collate code coverage results
dotnet test -c Release --no-build --no-restore Domain/SharedKernel/Dibware.Salon.Domain.SharedKernel.UnitTests/Dibware.Salon.Domain.SharedKernel.UnitTests.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=opencover
I did not use a sonar-project.properties file.
HTH someone, one day
