JUnit run configurations append spring.datasource parameters to java command

I'm working on a Spring Boot project including JDBC and Spock Framework tests.
Inside both production and test `application.yml` file I have configured Spring's DataSource in the following way:

url: jdbc:postgresql://localhost:5432/dbname
username: dbuser
password: changeme

After writing the first JDBC-based test, I tried running it using the 'play' symbol displayed next to a method declaration. This, as expected, created a JUnit run configuration. However, executing this configuration runs this command:

/home/max/.jdks/temurin-17.0.2/bin/java -ea -Dspring.datasource.username=postgres -Dspring.datasource.password=postgres <censored>

Which in turn causes test unit to fail due to datasource authentication error. I have checked the run configuration for environment variables or CLI argument that might cause this behavior, but found nothing. The only VM options are `-ea` and user's environment variables is empty.

I have a single PostgreSQL instance configured in this project, however its credentials are different and actually correct.

I've searched through `.idea` directory for files containing `postgres` substring and did not find anything subjectively relevant.

What else might possibly cause this behavior?


Which version of IDE do you use? Can you check if your yml file is configured as configuration file in File | Project Structure | Facets | Spring?


Yes, the configuration file is added.
