System property `powsybl.config.dirs` ignored in child module execution

[samirromdhani]

Describe the current behavior

When running the Maven command:

mvn clean package exec:exec@run

the powsybl.config.dirs property is ignored.

The console always shows:

INFO com.powsybl.commons.config.PlatformConfig - Platform configuration defined by YAML file /home/user/.itools/config.yml

PlatformConfig does not recognize the powsybl.config.dirs system property defined in the plugin, and continues to load the default YAML from the user home directory.

The plugin has the following configuration.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <configuration>
        <systemProperties>
            <systemProperty>
                <key>powsybl.config.dirs</key>
                <value>${project.basedir}/src/main/resources</value>
            </systemProperty>
        </systemProperties>
    </configuration>
</plugin>

Describe the expected behavior

PlatformConfig should load the config.yml from the directory specified in powsybl.config.dirs (src/main/resources).

Describe the steps

1. Place config.yml in the src/main/resources folder of the module (like loadflow or merging).
2. Run the Maven command as described in the README for the module you want to test.

mvn clean package exec:exec@run

3. Observe the console output.
   You should see that PlatformConfig does not load the config.yml from src/main/resources and instead uses the default YAML from the user home directory.

Extra Information

It appears that systemProperties defined in the child module are not applied when the execution is defined in the parent module.
