The frontend module pom is just configured with:
<plugin>
<groupId>com.github.eirslett</groupId>
<artifactId>frontend-maven-plugin</artifactId>
<version>1.12.1</version>
<configuration>
<workingDirectory>./</workingDirectory>
<nodeVersion>v18.8.0</nodeVersion>
<npmVersion>8.18.0</npmVersion>
</configuration>
<executions>

<configuration>

</configuration>

</plugin>
And in angular.json I just changed the target to get the maven clean plugin working without extra configuration:
"outputPath": "target/frontend",
Result when inside the module directory:

Why the the execution id npm run build is executed twice ?
Context: java 17 & angular 14
Root cause found: removing maven-surefire-report-plugin from parent pom (declared in pluginManagement) solves the problem.
I have no explanation.
