SonarCloud Analysis is failing in Azure DevOps pipeline with Gradlew build

  1. SonarQube scanner for Gradle plugin version ----------> 2.6.1

  2. error observed ------> Validation of project reactor failed:
    o “Customer App” is not a valid project or module key. It cannot be empty nor contain whitespaces.
    o “Customer App:app” is not a valid project or module key. It cannot be empty nor SonarQube scanner

  3. steps to reproduce ----------->
    a) I have configured the SonarQube scanner in DevOps pipeline using gradlew build.
    b) Run the pipeline. Getting above mentioned error.

The error message is pretty self-explanatory, isn’t it?

You can’t have any whitespace in your SonarCloud project key. So just change it to “customerapp” or something like that.

It would also help if you could share your azure-pipelines.yml.


I am using the classic editor to create a pipeline without YAML.

Using following plugin

  1. Prepare Analysis Configuration

  1. Gradle ( gradlew build)

According to this link the Sonar project key defaults to [{}:]{} with Gradle, so you probably should take a look at that or set the project key manually yourself.
