Sonarcloud is not authorized using Travis CI and Maven

I have an experimental project on my Github used for the practising the CI service integrations. I struggle with using Sonarcloud.

I have followed both Tavis CI + Sonarcloud tutorial and Maven example. Mz first confusion starts with the token and properties file whereas the first source suggests creating sonar-project.properties file and the Maven example source does not have any. Here where the documentation is very unclear.

I ignored the properties file and I have done the following steps:

1. Generated token on sonarcloud.io for my project: e53.....239

2. Encrypted token on travis-encrypt.github.io since it's the most comfortable way for a Windows user. The 2 following inputs resulted in g3s.....+Q=:

   • NicharNET/Gistintex
   • SONAR_TOKEN="e53...239" - I tried both to wrap between quotation marks and without.

3. Added to Settings -> Environment variable key SONAR_TOKEN with the value of the generated Sonarcloud token e53...239.

4. Completed travis.yml with the secure token:

   language: java
   sudo: false
   jdk: oraclejdk8
   
   addons:
       sonarcloud:
       organization: "nicharnet-github"
       token:
           secure: "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"
   
   script:
       - mvn clean install org.jacoco:jacoco-maven-plugin:prepare-agent sonar:sonar
   

5. Committed and pushed changes into the repository and Travis CI started to work and resulted in:

   Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.4.1.1168:sonar (default-cli) on project gistintex: Not authorized. Please check the properties sonar.login and sonar.password.

The error could be found on my Travis CI build. What do I do wrong?

I have skimmed through Error using Travis CI with Sonarcloud: Not authorized. Please check the properties sonar.login and sonar.password SO question and Travis CI Sonarqube analysis article, which unfortunately didn't help me though. My GitHub project source.

I have tried to add these plugins to pom.xml and run the analysis locally:

• org.codehaus.mojo: sonar-maven-plugin: 5.1
• org.sonarsource.scanner.maven: sonar-maven-plugin: 3.4.1.1168

Running this on my machine resulted in the correct Sonarcloud analysis:

mvn sonar:sonar \
   -Dsonar.organization=nicharnet-github \
   -Dsonar.host.url=https://sonarcloud.io \
   -Dsonar.login=e53.....239

However, my goal is to run the analysis after every committed version using Travis CI. I am sure I have done wrong the key encryption but I can't figure what exactly.
